Task: Answer the multiple choice question.
Question: Which drug has a -0.018\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) O=C(c1ccco1)N1N=C(c2ccc3nccnc3c2)CC1c1ccccc1
b) CC(Sc1n[nH]c(N)n1)C(=O)C12CC3CC(CC(C3)C1)C2
c) COc1ccc(NC(=O)CNS(=O)(=O)c2cccs2)cc1
d) O=C(Nc1ccc(Cl)c([N+](=O)[O-])c1)Nc1nc2ccccc2s1
Answer: a. O=C(c1ccco1)N1N=C(c2ccc3nccnc3c2)CC1c1ccccc1
