Task: Answer the multiple-choice question.
Query: Which drug exhibits a 7.560\% 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.) CCOC(=O)C1CCCCC12C(C#N)=C(N)Oc1n[nH]c(C)c12
b.) COc1ccc(NC(=O)CC(c2ccccc2)c2ccco2)cc1
c.) CCOCCCNC(=O)C(NC(=O)c1ccc(=O)[nH]c1)c1ccccc1
d.) CCc1sc(C(=O)NC)cc1Br
Answer: d. CCc1sc(C(=O)NC)cc1Br
