Let's go through these one by one

the set {a 35 year old adult} includes both men and women, agreed?

anonymous · Answer

yes it does

jim_thompson5910 · Answer

so because men are part of the set {a 35 year old adult} but NOT part of the set : {women between the ages of 30 and 40}, this means that choice A is NOT a subset

jim_thompson5910 · Answer

does that make sense?

jim_thompson5910 · Answer

Another example:

the set {women under 30}  is also NOT a subset because the original set is women between 30 and 40....but {women under 30}  is talking about a group of younger women.

You can use these ideas to either find the actual answer or eliminate bad choices until you're left with one choice (which has to be the answer)
