Task: Answer the multiple-choice question.
Question: Which drug exhibits a 2.878\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: COc1ccc(N/N=C/c2c(O)n(-c3cccc(C)c3)c(=O)[nH]c2=O)cc1
b: CCOC(=O)Cn1c(=O)oc2cc(S(=O)(=O)Nc3c(C)cc(C)cc3C)ccc21
c: CN(C)c1ncc(CN2CCC(CO)(CCCc3ccccc3)CC2)s1
Answer: a. COc1ccc(N/N=C/c2c(O)n(-c3cccc(C)c3)c(=O)[nH]c2=O)cc1
