Task: Answer the multiple choice question.
Query: Which compound exhibits a -15.140\% 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 other words.
Options:
a. CCOC(=O)N1CCN(C(=O)CN(Cc2ccc(Cl)cc2)S(=O)(=O)c2ccccc2)CC1
b. Cc1cc(N/N=C/c2cccc(Br)c2)nc2ccccc12
c. C#CCOC(=O)CCC(=O)NCCc1ccccc1
d. O=C(CCCO)N/N=C/c1cc(Br)ccc1O
Answer: a. CCOC(=O)N1CCN(C(=O)CN(Cc2ccc(Cl)cc2)S(=O)(=O)c2ccccc2)CC1
