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.
