Task: Answer the multiple-choice question.
Question: Which compound has a 3.806\% 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 other words.
Options:
a) C=CCn1c(=NC(=O)c2cc(Cl)sc2Cl)sc2cc(S(N)(=O)=O)ccc21
b) CCC1(c2ccc(F)cc2)NC(=O)N(CC(=O)Nc2cccnc2Cl)C1=O
c) O=C(CSc1nc2ncc(Br)cc2[nH]1)c1ccc([N+](=O)[O-])cc1
d) CC(=O)c1cccc(NC(=O)C(C)OC(=O)CCCN=C2NS(=O)(=O)c3ccccc32)c1
Answer: b. CCC1(c2ccc(F)cc2)NC(=O)N(CC(=O)Nc2cccnc2Cl)C1=O
