I think their answer is perfectly sensible and perfectly grammatical. It's also clearly correct according to even the most basic notion of slope as rise over run. I honestly don't see the issue with this question. Not only does your answer not fit grammatically, but it's also less precise.

When I skimmed the list of answers, they also looked wrong to me, but this is because I saw the answers (which start at the top of the page) before the question (which is at the bottom). Because the answers started with capital letters, I initially read them expecting a full sentence, mentally replacing "increase" with "increases": "The predicted height increases in centimeters for one centimeter increase in the first metacarpal bone." (True, although the height also increases in any other unit for any amount of increase in the bone.) "The predicted first metacarpal bone increases in centimeters for every centimeter increase in height." (Ditto, but this looks more correct because it has it increasing for every/any centimeter increase in height, rather than specifically one.) Judging by the parent comment, I think they may have done the same, but failed to notice the correct interpretation? In any case, while as a native speaker, I only saw it that way for a few seconds, I can certainly imagine that someone speaking English as a second language could be thrown off. The answers also do have odd wording - they refer to the bone itself "increasing", rather than its length, and the first answer's "for one centimeter increase" could be interpreted as either "for (one centimeter) increase", which lacks an article, or "for one (centimeter increase)", which is not ambiguous but not proper terminology either. I think the design could be improved - first by avoiding the weird inverted question/answer position if at all possible, second by avoiding capital letters, third by using easier to parse wording: "the predicted increase in height, in centimeters, for every one centimeter increase in the length of the first metacarpal bone"
