Task: Answer the multiple choice question.
Query: Which drug exhibits a -13.634\% 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.) CCOC(=O)/C=C/C(=O)OCC(=O)Nc1ccc(C)cc1
b.) Cc1ccn2cc(CC(=O)O)nc2c1
c.) Cc1nc(C)c2c(=O)cc(-c3ccccc3)[nH]c2n1
d.) CC(=O)c1cccc(NC(=O)c2ccc(OC3CSC3)cc2)c1
Answer: c. Cc1nc(C)c2c(=O)cc(-c3ccccc3)[nH]c2n1
