Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 6.344\% 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. Cc1cccc(C(=O)NN2S(=O)(=O)c3ccccc3S2(=O)=O)c1
b. COc1ccc(-n2nccc2-c2cc(Cl)sc2Cl)cc1
c. CCn1c(=O)c(C(=O)NCc2ccccc2Cl)c(O)c2ccccc21
d. C/C=C(\C)C(=O)Nc1cccc(C2=NOC3(C2)C[C@@H](C(N)=O)N(C(=O)c2cc([N+](=O)[O-])cc([N+](=O)[O-])c2C)C3)c1
Answer: b. COc1ccc(-n2nccc2-c2cc(Cl)sc2Cl)cc1
