Task: Answer the MCQ question.
Question: Which drug exhibits a 8.374\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: COc1cccc(OCc2ccc(C(=O)NCC3CCCO3)cc2)c1
b: CC(=O)C1=C(C)NC(C)=C(C(C)=O)C1c1cn(-c2ccccc2)nc1-c1cccs1
c: COc1cc(OC)c(C(=O)OCCCOC(=O)c2cc(OC)c(OC)cc2OC)cc1OC
d: Cc1ccc(-c2nnn(CC(=O)N(Cc3cccs3)C(C(=O)NC3CCCC3)c3ccco3)n2)o1
Answer: b. CC(=O)C1=C(C)NC(C)=C(C(C)=O)C1c1cn(-c2ccccc2)nc1-c1cccs1
