Which of the following is developed to result in the answer of 1?

A. 3(8^0)
B. 13-(7.42)^0
C. 5^0+9^0
D. (-2.97)^0

The only option among the given choices that results in the answer of 1 is:

C. 5^0 + 9^0

Any number raised to the power of 0 is equal to 1. So, 5^0 = 1 and 9^0 = 1. Therefore, 5^0 + 9^0 = 1 + 1 = 2, which is the answer.
