Task: Answer the multiple-choice question.
Query: Which drug exhibits a 2.904\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: O=C(C1=COCCO1)N1CCN(C(c2ccccc2)c2ccccc2)CC1
b: CCc1cc2cc(C)cc(C)c2nc1SCC(=O)N1CCCC1
c: COc1ccc(N2CCN(C(=O)c3ccc(CNS(=O)(=O)c4cccc(OC)c4)cc3)CC2)cc1
d: Cc1nc2ccccc2cc1C(=O)NCc1ccc(F)cc1
Answer: a. O=C(C1=COCCO1)N1CCN(C(c2ccccc2)c2ccccc2)CC1
