Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 8.860\% 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. CCC(=O)Nc1c(-c2cccs2)c(=O)c2ccccc2n1C
b. O=c1[nH]c2ccc(S(=O)(=O)NCCO)cc2[nH]1
c. CCN(CC)CCN1C(=O)C(=O)/C(=C(/O)c2ccc(S(=O)(=O)N3CCOCC3)cc2)C1c1ccc(C(C)C)cc1
d. CCc1nnc(NC(=O)CCC(=O)NCc2ccccc2Cl)s1
e. COc1ccc(NC(C)=O)cc1CNC(=O)COc1c(C)c(C)cc(C)c1C
Answer: a. CCC(=O)Nc1c(-c2cccs2)c(=O)c2ccccc2n1C
