Task: Answer the multiple choice question.
Query: Which drug exhibits a 3.923\% human ether-à-go-go related gene (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] CN=c1scc(-c2cccs2)n1/N=C(\C)c1ccco1
[b] C#CCNC(=O)C1=C[C@@H](C2CCCCC2)C[C@@H](OCCCCO)O1
[c] CCC(=O)N(Cc1cc2ccccc2[nH]c1=O)C(C)C
[d] CCOC(=O)c1c(C)[nH]c(C(=O)COC(=O)CNC(=O)c2ccc(Br)cc2)c1C
[e] O=C(OCc1nnc(-c2ccccc2)o1)C1=COCCO1
Answer: e. O=C(OCc1nnc(-c2ccccc2)o1)C1=COCCO1
