Task: Answer the multiple choice question.
Query: Which drug exhibits a 18.666\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] S=C(NCCc1c[nH]c2ccccc12)NC1CCCCC1
[b] CN1CCN(/N=C/c2ccc(C#N)cc2)CC1.Cl
[c] Cc1cccc(C(=O)NCc2nnc(SCC(=O)NC(C)c3ccccc3)n2C)c1
[d] CC1CN(Cc2ccccc2)c2nc3c(c(=O)n(CC(N)=O)c(=O)n3C)n2C1
[e] COc1ccc(OC)c(NC(=O)CSc2nnc(-c3ccncc3)s2)c1
Answer: d. CC1CN(Cc2ccccc2)c2nc3c(c(=O)n(CC(N)=O)c(=O)n3C)n2C1
