Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 5.484\% 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) N/C(=N\N=C\c1cccs1)SC1CC(=O)N(c2cccc([N+](=O)[O-])c2)C1=O
b) O=c1oc2ccccc2cc1N1CCOCC1
c) COc1ccc(-c2ccc(-c3noc(C)n3)c(OC)n2)cc1
Answer: b. O=c1oc2ccccc2cc1N1CCOCC1
