Here is the reason why:

Given: (A it true or B is true) implies C is true. That is, (A it true or B is true) is sufficient for C is true.
To prove: (A it true and B is true) implies C is true. That is, (A it true and B is true) is sufficient for C is true.

Proof:
Clearly, (A it true and B is true) implies (A it true or B is true). Since, (A it true or B is true) implies C is true. Hence, (A it true and B is true) implies C is true. Thus, (A it true and B is true) is sufficient for C is true.
