Problem statement: Answer the MCQ question.
Query: Which drug exhibits a 4.138\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: Cc1cc(C)nc(-n2nc(C)cc2NC(=O)c2cc3ccccc3oc2=O)n1
b: O=C(NCc1cc(C(F)(F)F)cc(C(F)(F)F)c1)C1CC(c2ccccc2C(F)(F)F)=NO1
Answer: b. O=C(NCc1cc(C(F)(F)F)cc(C(F)(F)F)c1)C1CC(c2ccccc2C(F)(F)F)=NO1
