Been studying consistently for around a month also, and can tell you with confidence you start to see the patterns more easily the more you practice (especially in SA questions like these). For this question, notice how answer choice B is the only answer that relates the ability to morally judge human character with having unambiguous and clear moral beliefs. We know that's what to look for since it bridges the gap between our second premise and our conclusion. Once you see what needs to be filled for the conclusion to make sense, start hunting for that answer right away.

Hope this helps

Yeah 44 minutes spent on a question that has a target time of less than a minute isn't very helpful
