Task: Answer the multiple-choice question.
Question: Which drug exhibits a 4.183\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: COc1ccccc1-n1ccnc1SCC(=O)NC(C)(C)C
b: O=C(NCCCN1CCCC1=O)c1ccc2c(=O)n(-c3ccccc3F)c(=S)[nH]c2c1
c: COCC(=O)Nc1cc(C(=O)Nc2cccc(C)c2C)ccc1Cl
d: Cc1nc2ccccc2c2c1CC(C)S2
e: COc1ccc(N2C(=O)C(F)(F)C2c2ccc(C)cc2)cc1OC
Answer: b. O=C(NCCCN1CCCC1=O)c1ccc2c(=O)n(-c3ccccc3F)c(=S)[nH]c2c1
