Task: Answer the multiple-choice question.
Question: Which drug has a 21.082\% 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 other words.
Options:
a: COc1cccc(/C=N/n2c(CO)nc3ccccc32)c1OC
b: COc1ccc(NC(=O)c2cccc(S(=O)(=O)N(C)c3ccccc3)c2)cn1
c: Cc1cc2ccccn2c1C(=O)c1ccc([N+](=O)[O-])o1
Answer: a. COc1cccc(/C=N/n2c(CO)nc3ccccc32)c1OC
