Task: Answer the multiple choice question.
Question: Which drug exhibits a 1.912\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a COCCNC(=O)Nc1ccc2nc(C)sc2c1
b COCc1ccc(CN2CCCC(C(=O)c3sccc3C)C2)o1
c O=C(c1ccc2c(c1)CCN2S(=O)(=O)c1ccccc1)N1CCN(c2ccccc2F)CC1
Answer: a. COCCNC(=O)Nc1ccc2nc(C)sc2c1
