Task: Answer the multiple-choice question.
Question: Which drug has a 0.005\% 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 CC1=C(C(=O)Nc2ccccc2)C(c2ccccc2[N+](=O)[O-])NC(=O)N1
b CC1CC(=O)Nc2ccccc2N1C(=O)CN1CCN(c2ccccc2)CC1
c CCOc1ccccc1NC(=O)C(NCCN(C)C)c1ccccc1.O=C(O)C(=O)O
d Cc1ccc(C(=O)Nc2c(C(=O)NCc3ccco3)cnn2-c2ccccc2)cc1
e COc1ccc(CCNC(=O)c2ccc(=O)[nH]c2)cc1OC
Answer: a. CC1=C(C(=O)Nc2ccccc2)C(c2ccccc2[N+](=O)[O-])NC(=O)N1
