Task: Answer the multiple-choice question.
Query: Which drug exhibits a 11.112\% 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] O=C(Nc1ccc(N2CCCC2)cc1)c1cc(Br)ccc1Cl
[b] O=C(Nc1cccc2ncccc12)c1ccc(Br)c([N+](=O)[O-])c1
[c] O=S(=O)(O/N=C1\CCCc2ccccc21)c1ccc(Cl)cc1
[d] CCCCN(C)C(=O)c1nc2ccccn2c1CN1CCSCC1
[e] Cc1oc(-c2cccc(Cl)c2)nc1CS(=O)(=O)CC(=O)NC1CCCC1
Answer: a. O=C(Nc1ccc(N2CCCC2)cc1)c1cc(Br)ccc1Cl
