Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 2.123\% 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 COc1cccc(-c2nc3ccc(N4CCN(C)CC4)cc3[nH]2)c1
b O=C(O)CSc1c2c(nc3cc(C(=O)N4CCCC4)ccc13)CCCC2
c O=C(CSc1nnc(-c2ccccc2)o1)Oc1ccc(Br)cc1
d COc1ccc(NC(=O)c2ccc3c(=O)n4c(nc3c2)CCCCC4)cc1
e COC(=O)c1cc2n(n1)CCN(Cc1ccccc1Cl)C2=O
Answer: b. O=C(O)CSc1c2c(nc3cc(C(=O)N4CCCC4)ccc13)CCCC2
