Task: Answer the multiple-choice question.
Query: Which drug exhibits a 3.347\% 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) Cl.N=c1n(CCO)c2ccccc2n1Cc1ccccc1
b) Cn1c(SCc2cccc([N+](=O)[O-])c2)nc2c(c1=O)SCC2
c) N/C(Cc1cccc2ccccc12)=N\OC(=O)Cc1cccs1
Answer: b. Cn1c(SCc2cccc([N+](=O)[O-])c2)nc2c(c1=O)SCC2
