Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -64.807% 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 additional words.
Options:
a. CC(C)(C)c1ccc(OCCC(=O)NCC(c2cccs2)N2CCOCC2)cc1
b. CCCCCOC(=O)C1=C(C)NC(=O)NC1c1ccc([N+](=O)[O-])cc1
c. CCOC(=O)C1CCCN(C(=O)/C=C/c2ccc([N+](=O)[O-])cc2)C1
d. CCCCN1CC2([N+](=O)[O-])C=CC(=O)C([N+](=O)[O-])(C1)C2CC(=O)c1ccccc1
Answer: c. CCOC(=O)C1CCCN(C(=O)/C=C/c2ccc([N+](=O)[O-])cc2)C1
