Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -12.336\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] CCc1sc(C(=O)Nc2ccc3c(c2)OCCO3)cc1Br
[b] Cc1c(C(=O)Nc2ccccc2[N+](=O)[O-])csc1-c1ccccc1
[c] Cc1ccc(N2C(=O)CSC2c2c(F)cccc2Cl)cc1
Answer: b. Cc1c(C(=O)Nc2ccccc2[N+](=O)[O-])csc1-c1ccccc1
