Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 13.784\% 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.) OCn1ncn(-c2ccccc2)c1=S
b.) O=C(CN1C(=O)NC2(CCCc3ccccc32)C1=O)Nc1cccc(S(=O)(=O)N2CCCCC2)c1
c.) CCCN(CC(=O)Nc1ccccc1C)C(=O)c1ccc(N2CCCC2=O)cc1
d.) CC(C)(C)c1nn2cnnc2n(/N=C/c2ccccc2)c1=O
Answer: a. OCn1ncn(-c2ccccc2)c1=S
