Task: Answer the multiple choice question.
Question: Which drug exhibits a -16.454% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] O=C(c1cnccn1)N(Cc1cccs1)C1(C(=O)NC2CCCCC2)CCCCC1
[b] CSc1ncccc1C(=O)Nc1ccncc1
[c] O=C(COC(=O)c1cccc(-n2cnnn2)c1)c1ccc(F)cc1
[d] O=C(Nc1nc(-c2ccccc2)cs1)C1CCCN(S(=O)(=O)c2cccc([N+](=O)[O-])c2)C1
[e] C/C(=N/Nc1ncc(Br)cn1)c1ccc(Br)cc1
Answer: a. O=C(c1cnccn1)N(Cc1cccs1)C1(C(=O)NC2CCCCC2)CCCCC1
