Task: Answer the MCQ question.
Query: Which drug has a 8.186\% 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 C=CCn1c(=O)[nH]c2cc(C(=O)N3CC=C(c4ccccc4)CC3)ccc2c1=O
b COc1ccc(CCN2CC(C(=O)N(C)Cc3ccc(C)o3)CCC2=O)cc1
c CN1C(=O)C(O)(c2nnc(-c3ccccc3)o2)c2ccccc21
d O=C(Nc1cc(Cl)ccc1F)c1ccc(-n2cncn2)c([N+](=O)[O-])c1
Answer: c. CN1C(=O)C(O)(c2nnc(-c3ccccc3)o2)c2ccccc21
