Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 5.507\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) N#CC1=C(N)OC2=C(CC/C2=C\c2ccc(F)cc2)C1c1ccc(F)cc1
(b) CCCNC(=O)C(Cc1cccc(Cl)c1)NC(=O)c1ccc(C#N)cc1
Answer: a. N#CC1=C(N)OC2=C(CC/C2=C\c2ccc(F)cc2)C1c1ccc(F)cc1
