Task: Answer the multiple-choice question.
Query: Which drug exhibits a 4.449\% 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] COCCNC(=S)NCc1ccc2[nH]c3c(c2c1)CCCC3
[b] CCN(CC(=O)NCc1cccs1)C(=O)/C=C/c1ccc(OC)c(OC)c1
[c] Cc1csc(NC(=O)CSc2nnc(-c3ccccc3)o2)n1
[d] Cc1c(C(=O)Nc2c(F)cccc2F)sc2ncnc(N3CCN(c4ccccc4)CC3)c12
[e] CCOc1ccccc1C(=O)Nc1ccc(S(=O)(=O)Nc2nccc(C)n2)cc1
Answer: b. CCN(CC(=O)NCc1cccs1)C(=O)/C=C/c1ccc(OC)c(OC)c1
