Task: Answer the multiple choice question.
Question: Which drug exhibits a 3.011\% 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: COc1cccc(C(=O)Nc2c3c(nn2-c2cccc(C)c2C)CS(=O)(=O)C3)c1OC
b: COCc1ccc(C(=O)N2CCCC(C(=O)c3ccc(SC)cc3)C2)s1
c: Cc1ccc(C(=O)NC(=S)Nn2cnnc2)cc1
d: CCOC(=O)Cn1c(C)[n+](C)c2cc(Cl)c(Cl)cc21.[I-]
e: NC(=O)C1CCN(C(=O)Cc2ccc(-c3ccccc3)cc2)CC1
Answer: b. COCc1ccc(C(=O)N2CCCC(C(=O)c3ccc(SC)cc3)C2)s1
