Task: Answer the multiple choice question.
Question: Which drug exhibits a 13.321% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. O=C(Nc1ccccc1C(F)(F)F)c1cccnc1
b. O=C(Nc1ccc(S(=O)(=O)NC2CCCCC2)cc1)c1ccc(Br)o1
c. O=c1[nH]c(-c2ccccc2)c(-c2ccccc2)[nH]1
d. COc1cccc(NC(=O)CCc2nc(-c3cccs3)no2)c1
Answer: c. O=c1[nH]c(-c2ccccc2)c(-c2ccccc2)[nH]1
