Which example supports the given conjecture?

The sum of three odd numbers is an odd number

a. 3 + 5 + 7 = 15

b. 1 + 2 + 3 = 6

c. 2 + 4 + 8 = 14

d. 4 + 5 + 6 = 15

The answer choice A

because answer choice A has all odd numbers on the L. H. S. and the sum on those number is odd

It is not B because although it has odd numbers on L. H. S., their sum equals even number

It is not C because it has even number on L. H. S.

It is not D because it has even number on L. H. S.
