Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -2.942% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CCOC(=O)c1nn(-c2ccc(C)cc2)cc1O
b: CC(=O)NCCc1ccc(C(=O)CSc2nnc(C3CC3)n2C2CC2)cc1
c: CCC(CC)CN1C(Nc2ccccc2)=NC[C@@H]1C
d: COc1ccc(CNC(=O)c2cc(=O)c3ccccc3o2)cc1
Answer: c. CCC(CC)CN1C(Nc2ccccc2)=NC[C@@H]1C
