Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 18.258\% 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 COc1ccc(CC(=O)NNS(=O)(=O)c2ccc3ccccc3c2)cc1OC
b Cn1nc(C(=O)N2CCc3ccccc32)c2ccccc2c1=O
c O=C(C1CC(=O)N(c2ccc(Cl)cc2)C1)N1CCC(c2nc3ccccc3[nH]2)CC1
d CC(C)CC(=O)/C(=C/c1ccc(N(C)C)cc1)n1cncn1
Answer: b. Cn1nc(C(=O)N2CCc3ccccc32)c2ccccc2c1=O
