Task: Answer the multiple choice question.
Query: Which drug exhibits a -20.888\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a Cn1c(SCc2cccc(C#N)c2)nc2ccccc2c1=O
b COCc1cc(C)nc(NCCO)c1C#N
c O=C(c1cccnc1)N1CCN(S(=O)(=O)c2ccc3ccccc3c2)CC1
d CCc1ccc(NC(=O)CCc2ccc(CC)o2)cc1
e O=C(O)CCc1nc2cc(Cl)ccc2n(Cc2ccccc2)c1=O
Answer: c. O=C(c1cccnc1)N1CCN(S(=O)(=O)c2ccc3ccccc3c2)CC1
