Answer: Option C. -> Green

Answer: Option C. -> Anxiety

Answer: Option D. -> Watt
Ohm, volt, and ampere are units of electrical measurements. Ohm is the unit of electrical resistance, volt is the unit of electrical potential or electromotive force, and ampere is the unit of electric current.
Watt is the unit of electrical power, which is defined as the rate at which work is done or energy is transferred. It is named after James Watt, a Scottish engineer who made significant contributions to the development of the steam engine.
The formula for electrical power is given by:
Power (P) = Voltage (V) x Current (I)
where P is the power in watts (W), V is the voltage in volts (V), and I is the current in amperes (A).
Hence, the unit of power, watt, is equivalent to the product of the units of voltage and current, i.e., volt-ampere.
Light is not a unit of measurement. It refers to electromagnetic radiation that is visible to the human eye.
Metre is the unit of length in the International System of Units (SI).
Hour is the unit of time, which is equal to 60 minutes or 3,600 seconds.
In conclusion, option D, Watt, is the correct answer as it is the unit of electrical power, which is the product of voltage and current.

Answer: Option C. -> Man, Feminine

Answer: Option B. -> Bird, Water
The relationship between Sky and Blue is that the sky is typically blue in color. Similarly, the relationship between Fish and Water is that fish typically live in water and swim. Therefore, the correct answer to the given question is Bird, Water.
Let's understand some relevant definitions and formulas related to the answer:

• Analogy: An analogy is a comparison between two things that are typically different but have some similarities.
• A is to B as C is to D: This is a format commonly used to present an analogy question, where A and B have a certain relationship, and we need to find a pair C and D that have a similar relationship.

Using the above definitions, we can see that the analogy presented in the question follows the format of "A is to B as C is to D". In this case, we have:

• A = Sky
• B = Blue
• C = Fish
• D = ?

To find the correct answer, we need to identify the relationship between A and B and then find a similar relationship between C and D. The relationship between Sky and Blue is that the sky is typically blue in color. The relationship between Fish and the correct answer (D) should have a similar relationship, such as living or moving in water.
Option A (Blue, Swim) has one correct word (Swim), but Blue doesn't have a relationship with Fish.Option C (Open, Hook) and Option D (Tree, Colour) have no clear relationship with Fish.Therefore, Option B (Bird, Water) is the correct answer because birds often live near or in water bodies and are known to swim, dive or wade in water for food.
In conclusion, the correct answer to the given question is Option B: Bird, Water, which has a similar relationship to Fish as Sky has to Blue.If you think the solution is wrong then please provide your own solution below in the comments section .
