You should change your user name to Heredomyhomework. Have you even tried searching out this info for yourself. Here I helped you out.

Wikipedia is sometimes innacurate. Its not that I would be asking for you to do my homework. I do my homework myself but when I come upon an obstacle, I would like to seek for help in a community filled with scholars (biology-online.org).

If you lookup all 4(3 if you're smart enough to rule out water) choices on wikipedia, you'll find that one of them is excreted somewhere else.

fortunately for you, the question is stupid: the correct answer is: it contains all 4 of them

Uhm... isn't the question a bit ambiquous?

There's a difference whether it's "Which one of these is not found in sweat?" and "Which one of these is not secreted by sweat glands?" - now it says "...is not secreted by sweat", which doesn't quite make sense to me. Nor does this make any difference between eccrine and apocrine glands, of which the latter produce fatty substances, afaik (although eccrine glands probably secrete traces of fats too?). Or am I missing something now? I take it that by 'oil' the question refers to biological oils, that is, a type of lipid..?

no, but you should have let him figure that out for himself
