Task: Answer the multiple choice question.
Question: Which drug has a -0.773\% 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, or d without using any other words.
Options:
a: O=C(c1ccc(Cl)c(S(=O)(=O)N2CCCCCC2)c1)N1CCN(c2ccccn2)CC1
b: Cc1nnc(SCC(=O)N2CCN(S(=O)(=O)c3ccccc3)CC2)s1
c: CC(=O)OCCNc1cc(Sc2nc3ccccc3[nH]2)c2nonc2c1[N+](=O)[O-]
d: Cc1ccc(S(=O)(=O)Oc2cccc(/C=N/n3cnnc3)c2)cc1
Answer: a. O=C(c1ccc(Cl)c(S(=O)(=O)N2CCCCCC2)c1)N1CCN(c2ccccn2)CC1
