Task: Answer the multiple-choice question.
Question: Which drug exhibits a 2.788\% 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 other words.
Options:
[a] CC1=C(C(=O)Nc2ccc([N+](=O)[O-])cc2)C(c2cccc(C(F)(F)F)c2)NC(=S)N1c1ccccc1
[b] COc1ccccc1NC(=S)NCc1ccc(S(N)(=O)=O)cc1
[c] O=C1c2ccccc2C(=O)N1Cc1ccccn1
[d] Cn1c(CC(=O)NNC(=O)c2ccc(F)cc2F)nc2ccccc21
[e] O=C(O)c1cccc([N+](=O)[O-])c1C(=O)Nc1cccc2ccccc12
Answer: a. CC1=C(C(=O)Nc2ccc([N+](=O)[O-])cc2)C(c2cccc(C(F)(F)F)c2)NC(=S)N1c1ccccc1
