A
Correct answer
Explanation
Bhaskaracharya (Bhaskara II), the 12th-century Indian mathematician and astronomer, calculated the time taken by Earth to orbit the Sun in his work Siddhanta Shiromani (1150 AD). He determined it to be approximately 365.258 days, which is remarkably close to the modern value of 365.256 days. Einstein and Newton worked much later on different aspects of physics, and Galileo (misspelled as 'Gellilio') focused on astronomy and physics but not this specific calculation.
