Task: Answer the multiple choice question.
Query: Which compound exhibits a -5.570\% 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)CSc1nnc(-c2ccc(S(=O)(=O)N3CCOCC3)cc2)n1-c1ccccc1
b. O=C(Nc1ccc2c3c(cccc13)CC2)c1cccc([N+](=O)[O-])c1
c. Oc1ccccc1C1CC(c2cccs2)=NC(c2cccc(Br)c2)N1
d. N#Cc1cccnc1N1CCN(C(=O)c2ccc3c(c2)S(=O)(=O)c2ccccc2C3=O)CC1
Answer: d. N#Cc1cccnc1N1CCN(C(=O)c2ccc3c(c2)S(=O)(=O)c2ccccc2C3=O)CC1
