Task: Answer the multiple choice question.
Question: Which compound has a 3.962\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: COc1ccc(-c2cc(C(=O)N(C)Cc3ccccc3)no2)cc1OC
b: COc1ccc(C(=O)N2CCCCCC2)cc1S(=O)(=O)N1CCOCC1
c: CCCn1c(=O)[nH]c(=O)c2c1nc(-c1ccc(OC)c(Br)c1)n2CCOC
d: C=CCSc1nc2sc3c(c2c(=O)n1-c1ccc(C)cc1)CCN(C)C3
Answer: a. COc1ccc(-c2cc(C(=O)N(C)Cc3ccccc3)no2)cc1OC
