Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 0.239\% 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, or c without using any additional words.
Options:
a.) Cn1ccnc1Sc1nnnn1-c1ccccc1
b.) CCOC(=O)C1=C(C)N[C@@]2(O)c3ccccc3C(=O)[C@@]12O
c.) CC(C)(C)N/N=C/c1cc(Cl)cc([N+](=O)[O-])c1O.Cl
Answer: a. Cn1ccnc1Sc1nnnn1-c1ccccc1
