Task: Answer the MCQ question.
Question: Which compound exhibits a 13.709\% 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: O=c1[nH]c(=O)n(-c2ccc(Cl)cc2)c(O)c1C=Nc1ccc(S(=O)(=O)Nc2nccs2)cc1
b: CCCN1CCC(=O)N(CCOc2ccccc2)CC1
c: Cc1cccnc1NC(=O)c1ccc(S(=O)(=O)N2CCCCC2)cc1
d: COc1cccc(CNS(=O)(=O)c2cc3c(cc2C)n(C)c(=O)c(=O)n3C)c1
Answer: a. O=c1[nH]c(=O)n(-c2ccc(Cl)cc2)c(O)c1C=Nc1ccc(S(=O)(=O)Nc2nccs2)cc1
