Answer: Option A
Answer: (a)
In Harshavardhana court, a Chinese embassy was sent by the T’ang emperor. The T’ang dynasty was formed in 618 due to the failed exhibitions to Korea by the Sui, which had led to conflicts in the north of China.
The T’ang’s founder, Li Yuan was a rebel from an aristocratic family (traced from the Han) that was influential under the Northern Zhou. The T’ang took some time to become established, in part due to a rebellion in 617 that took several years to succeed with the help of the Turks.
