Task: Answer the multiple choice question.
Query: Which drug exhibits a -0.257\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. CC(C)CCNC1=CC(=O)CC(c2ccccc2)C1
b. CC1(c2ccccc2)NC(=O)N(CC(=O)Nc2ccccc2N2CCCCC2)C1=O
c. CC1CN=C(Nc2ccc(F)cc2)S1
d. Cc1ccc(-c2cc(C(F)F)nc(NCc3cccs3)n2)cc1
Answer: a. CC(C)CCNC1=CC(=O)CC(c2ccccc2)C1
