You are absolutely correct in saying that C "must" be a correct choice because the value of "a+b" is a subset of the inequality shown in choice C. But at the same time choice A & B are also correct, since the stem asks us about "which inequalities hold true" going by the definition, the values taken by "a+b" are also a subset of choice A & B. And I say subset because a+b>7 means that a+b can also be 7.0000001,7.000002 and so on, but since we know that a & b are integers we are ignoring such possibilities.
It’s maths and we can agree to disagree as well!
