Task: Answer the multiple choice question.
Query: Which compound exhibits a 9.202\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) O=C(Cc1ccc(Br)cc1)N1CCN(c2ccccc2)CC1
b) NNC(=O)c1sc(-c2ccccc2)cc1N
c) O=C(NCC(=O)N1CCCC1C(=O)O)OC1CCCCC1
d) CCOC(=O)NC(NC(=S)Nc1ccc(OC)cc1)C(Cl)(Cl)Cl
Answer: a. O=C(Cc1ccc(Br)cc1)N1CCN(c2ccccc2)CC1
