Task: Answer the multiple-choice question.
Query: Which drug has a 9.113\% 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. COc1ccc(NC(=O)Nc2ccncc2)c(OC)c1
b. OCC1(CCCc2ccccc2)CCN(Cc2cnc(N3CCOCC3)s2)CC1
c. O=C(Cn1cnc2ccccc21)Nc1ccccc1-c1ccccc1
