Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 2.019\% 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 other words.
Options:
[a] CN(C)CCNC(=O)C(C(=O)c1ccccc1)n1ccccc1=O.Cl
[b] COCCCNC(=O)CCc1nnc(Cc2ccc(-c3ccccc3)cc2)o1
[c] c1ccc(COCC2CCNCC2)cc1
[d] Cc1c(Cl)c(-c2n[nH]c(=S)n2Cc2ccco2)nn1C
[e] C=CCNC(=S)N(CC)c1cccc2ccccc12
Answer: e. C=CCNC(=S)N(CC)c1cccc2ccccc12
