Problem statement: Answer the MCQ question.
Question: Which drug has a -0.344\% human ether-à-go-go related gene (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 additional words.
Options:
a.) COc1ccc(S(=O)(=O)N2CCc3ccccc32)cc1OC
b.) Cc1ccc(S(=O)(=O)N2CCN(c3ccc([N+](=O)[O-])c4cccnc34)CC2)cc1
c.) CCCCn1c(O)c(C(C)=NC(C)c2ccccc2)c(=O)[nH]c1=O
d.) CCOC(=O)Cn1nc(C)c(NC(=O)c2ccc(Cl)c([N+](=O)[O-])c2)c1C
Answer: c. CCCCn1c(O)c(C(C)=NC(C)c2ccccc2)c(=O)[nH]c1=O
