D Correct answer
Explanation

Brahmagupta (598-668 CE) was the first mathematician to treat zero as a number and define its operations. In his work Brahmasphutasiddhanta (628 CE), he established rules for arithmetic with zero, including that zero multiplied by any number equals zero. Earlier mathematicians like Aryabhata used the place value system but Brahmagupta formalized zero as a number.
