Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 1.994\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a.) O=C(C1CCN(S(=O)(=O)c2ccc(Cl)cc2)CC1)N1CCOCC1
b.) O=C(N/N=C/c1cc(Cl)cc([N+](=O)[O-])c1O)c1cc(-c2ccccn2)nc2ccccc12
c.) Nc1nonc1-n1nnc(C(=O)N/N=C/c2cccc(Cl)c2)c1CSc1ccccc1
Answer: a. O=C(C1CCN(S(=O)(=O)c2ccc(Cl)cc2)CC1)N1CCOCC1
