Task: Answer the multiple-choice question.
Query: Which compound has a 2.737% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a. O=c1[nH]c2ccccc2cc1-c1noc(-c2cccnc2)n1
b. COc1cc(CN2CCCC(C(=O)c3ccccc3SC)C2)cc(OC)c1
c. CC(=O)Nc1ccc(NC(=O)c2ccccc2CCc2ccccc2)cc1
d. NS(=O)(=O)c1ccc(CCNC(=O)COC(=O)/C=C/c2ccc(Cl)cc2)cc1
e. CCOc1ccc(-c2nnc(NC(=O)CCCOc3cccc(C)c3)o2)cc1
Answer: a. O=c1[nH]c2ccccc2cc1-c1noc(-c2cccnc2)n1
