Task: Answer the MCQ question.
Query: Which drug exhibits a -56.267\% 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.) COc1ccc(C/C(C)=N/NC(=O)c2cc(C)oc2C)cc1
b.) CCC(C)NC(=O)CSc1nc2ccsc2c(=O)n1NC(=O)c1ccccc1
c.) O=C(OCc1ccc([N+](=O)[O-])cc1)C1CC(=O)N(CCc2ccccc2)C1
d.) O=C(O)/C=C/c1cn(Cc2ccccc2)nc1-c1cccnc1
Answer: c. O=C(OCc1ccc([N+](=O)[O-])cc1)C1CC(=O)N(CCc2ccccc2)C1
