B Correct answer
Explanation

Bhaskaracharya (Bhaskara II), the 12th-century Indian mathematician and astronomer, calculated the time taken by Earth to orbit the Sun as approximately 365.2588 days. This value is very close to the modern value and is documented in his work Siddhanta Shiromani. Aryabhatta had also worked on astronomical calculations but Bhaskara's calculation was more precise.
