Task: Answer the multiple choice question.
Query: Which drug exhibits a -2.532% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) CCn1nc(C(=O)Nc2nc(-c3ccccn3)cs2)c2ccccc2c1=O
(b) Cc1ccccc1-n1c(-c2ccc(=O)[nH]n2)n[nH]c1=S
(c) CC(Cc1ccccc1Sc1ccccc1O)N(C)C.Cl
(d) CN1CCN(NC(=O)c2cn(-c3ccccc3)nc2-c2cccc(Br)c2)CC1.Cl
(e) CCOC(=O)c1c(C)n(C)c2cc(Br)c(O)c(O)c12
Answer: a. CCn1nc(C(=O)Nc2nc(-c3ccccn3)cs2)c2ccccc2c1=O
