Task: Answer the multiple choice question.
Question: Which drug exhibits a 13.023\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: O=C1CSC(=S)N1c1cccc(Br)c1
b: CC(C)OC(=O)c1cc(=O)[nH]c2ccccc12
c: CN(C)c1ccc(C(=O)NCC2(N(C)C)CCCCC2)cc1
d: O=C(Nc1cc(S(=O)(=O)N2CCCCC2)ccc1N1CCCCC1)C1CC1
e: Cc1ccc(-c2nnc(SCC#N)n2N)cc1
Answer: a. O=C1CSC(=S)N1c1cccc(Br)c1
