Task: Answer the multiple-choice question.
Query: Which drug exhibits a 3.116\% 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] CC1(C)C(=O)N(c2ccccc2)C(=O)c2ccccc21
[b] COc1ccc(-c2nc3ccccc3s2)cc1NC(C)=O
[c] O=c1[nH]c(C2CCN(S(=O)(=O)c3ccc4c(c3)OCCO4)CC2)nc2c1nnn2Cc1c(F)cccc1Cl
[d] O=C(CSc1nc2ccc(Cl)cc2[nH]1)N1CCN(C(=O)c2ccco2)CC1
Answer: b. COc1ccc(-c2nc3ccccc3s2)cc1NC(C)=O
