Task: Answer the MCQ question.
Query: Which drug exhibits a 15.546\% 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. O=C(COC(=O)CCCN=C1NS(=O)(=O)c2ccccc21)NC(=O)NC1CCCC1
b. COc1ccc(/C=c2/sc3nc(-c4ccccc4)c(-c4ccccc4)n3c2=O)cc1
c. CC(=O)NC1C(OCc2ccccc2)OC(CO)C(OC(C)=O)C1OC(C)=O
Answer: a. O=C(COC(=O)CCCN=C1NS(=O)(=O)c2ccccc21)NC(=O)NC1CCCC1
