Task: Answer the MCQ question.
Question: Which drug has a 1.816\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: O=C(CSc1nnc(-c2ccc(Br)cc2)n1CCc1ccccc1)NC1CCS(=O)(=O)C1
b: COC(=O)c1cc2c(ccn2-c2ccc(F)cc2)n1Cc1cccc(OC)c1
c: Cn1nc(-c2ccccc2)c(N2CCCCC2)cc1=O
d: CNC(=O)C(=O)NCCC1CCCCN1S(=O)(=O)c1cccs1
e: CN(CC(=O)Nc1ccc(N2CCOCC2)cc1)CC(=O)Nc1ccccc1C#N
Answer: b. COC(=O)c1cc2c(ccn2-c2ccc(F)cc2)n1Cc1cccc(OC)c1
