IMO 'B'
1.i=10....no details for j...Not sufficient
2.i=j so i+j=2*i...which will always be even...sufficient..
What is the Original Answer?

OA is B,

But why i and j cannot equal to zero. because it is not mentioned that i and j are different integers .

therefore, i = j = 0,

then, B is also insufficient,

ans : e

If j = 0 and i = 0 and i + j = 0 then then B would still be the correct answer because 0 is an even integer. Does that make sense?

But dear, zero is neither positive nor negative integer.

To confirm "zero is neither positive nor negative integer" kindly check OG 11th Edition, page no.108 , last paragraph: properties of integers.

Answer must be B
0 is an even integer....which is neither +ve nor -ve

You are 100% correct - however, that has nothing to do with this question!

0 is an even "uncharged" integer.
