Task: Answer the multiple-choice question.
Question: Which drug exhibits a 16.763\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: CCOc1ccc(C2=C(C=C(C#N)C#N)C(c3ccccc3)c3ccccc3O2)cc1
b: CCCNC(=O)c1ccc2c(c1)ncn2-c1cc(C)cc(C)c1
c: CSc1nnnn1-c1c(C)cccc1C
d: O=C(NCc1ccco1)c1cccc(S(=O)(=O)N2CCc3ccccc32)c1
e: CCn1ccnc1CNC(=O)C1CCC(=O)N(Cc2ccccc2F)C1
Answer: a. CCOc1ccc(C2=C(C=C(C#N)C#N)C(c3ccccc3)c3ccccc3O2)cc1
