Task: Answer the multiple choice question.
Query: Which drug exhibits a -2.994\% 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. O=Cc1ccc(C(=O)O)cc1
b. O=C(NNC(=O)c1ccccc1)C(=O)N1CCCCC1
c. CSC(=O)CC(=O)NC(=O)c1ccccc1
d. CCC(CC)C(=O)NCCc1ccc(OC)c(OC)c1
Answer: b. O=C(NNC(=O)c1ccccc1)C(=O)N1CCCCC1
