Explanation:

First Question (Base - 10 Number System)

The base - 10 number system we use today is called Arabic Numerals. Greek numerals use a different system, European is not a specific numeral system name, Phoenician numerals are different, and Latin numerals (like I, II, III) are not the base - 10 system we use daily.

Muslim mathematicians and astronomers developed Algebra, in part, to simplify Islamic inheritance law. Geography is about places, Calculus was developed later (not for inheritance law), Geology is about the earth, and Cartography is about map - making. Algebra was useful for handling the mathematical problems related to inheritance distributions.

Answer:

A. Arabic
