Task: Answer the MCQ question.
Question: Which drug exhibits a 11.823\% 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 other words.
Options:
(a) O=C1c2ccccc2NC2CCCCCN12
(b) O=C(O)c1ccc2c(c1Nc1ccccc1)C(=O)c1ccccc1C2=O
(c) C/C(=N\N1CCN(Cc2ccc(Cl)cc2)CC1)c1ccc([N+](=O)[O-])cc1
Answer: b. O=C(O)c1ccc2c(c1Nc1ccccc1)C(=O)c1ccccc1C2=O
