Answer

Brief Explanations:

Al - Biruni made precise calculations of the Earth's radius. Al - Battani refined measurements of the solar year and planetary orbits. The heliocentric model was not discovered by al - Battani. The telescope was not invented by him either, and mapping the stars is not his most well - known contribution.

Answer:

First question: C. al Biruni Second question: B. Refining measurements of the solar year and planetary orbits
