Task: Answer the multiple-choice question.
Query: Which drug exhibits a 4.920\% 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.) CSc1cccc(NC(=O)COc2ccccc2)c1
b.) O=C(CSc1nnc(-c2ccco2)n1-c1ccccc1)N1CCN(C(=O)c2ccco2)CC1
c.) CC1(C)CC(=O)C2=C(C1)Nc1ccccc1NC2c1ccc2c(c1)OCO2
d.) O=C(N/N=C/c1cccc([N+](=O)[O-])c1O)c1cccs1
e.) COc1cc2c(cc1OC)C(C(=O)NCc1ccco1)C(c1cccs1)N(C)C2=O
Answer: b. O=C(CSc1nnc(-c2ccco2)n1-c1ccccc1)N1CCN(C(=O)c2ccco2)CC1
