Answer & ExplanationAnswer: [B]
During the post-Gupta period in India, which lasted from the 7th to the 12th century CE, one of the primary items that was mostly imported into India was horses (option B). Horses were highly valued for military purposes and played a crucial role in warfare, transportation, and trade during that time. The importation of horses into India was particularly significant because the native Indian breeds were relatively smaller and less suited for certain purposes compared to the larger and stronger Central Asian and Arabian breeds. Therefore, the import of horses was crucial for maintaining the military and economic power of various kingdoms and empires in India during the post-Gupta period.
