Task: Answer the multiple choice question.
Question: Which drug exhibits a -1.987\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: Cc1c(Nc2ccc(C=O)cc2)c(=O)n(-c2ccccc2)n1C
b: C=CCSc1nc2c(cnn2-c2ccc(C)c(C)c2)c(=O)[nH]1
c: Fc1cccc(CCN2CCNC[C@H]2Cc2cccc3ccccc23)c1
d: Cc1cc(C)c(S(=O)(=O)Cc2ccccc2)c(OC(C)C)n1
Answer: a. Cc1c(Nc2ccc(C=O)cc2)c(=O)n(-c2ccccc2)n1C
