Irrational numbers are defined as those numbers which havea non-terminating and non-repeating decimal expansion and hence cannot be represented in the pqform. So, here we see that out of the given options the number 5.2731687143725186..... has a non-terminating and non-repeating decimal expansion as clearly one can interpret that there are no patterns formed in the decimal expansion and the number goes on expanding arbitrarily.
