As soon as I read the sentence, there is a comparison of X and Y as we have a marker of "Unlike". And we need to compare correct nouns to correct nouns.
So, for the non - underlined part, the type of ants are compared, so we need type of ants at the beginning.
Hence A,B and E goes off.
Next, Unlike X, Y does Z -> is the correct structure. So, we need an action describing what Y does that X doesn't do.
If we need to add extra information, we need a modifier. Option C) does exactly that.
For option D) in having -> looks like an action for X which is not correct. And besides, that, having is used for possessive form.
