Task: Answer the multiple-choice question.
Query: Which drug exhibits a 5.730\% 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. COc1cnc(-c2ccccn2)nc1Sc1ccccc1Cl
b. COc1ccc(/C(N)=N/OC(=O)/C=C/c2ccccc2)cc1
