Task: Answer the multiple choice question.
Question: Which compound exhibits a 19.261\% 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 CCO/C=C1\C(=O)N(c2ccc(OCC)cc2)C(=O)c2ccccc21
b CC(C)(C)N1C(=O)c2ccc(C(=O)O)cc2C1=O
c COc1ccc(C(=O)COC(=O)Cn2c(C)csc2=O)c(OC)c1
d N#Cc1ccccc1NC(=O)c1cc(=O)c2ccccc2o1
Answer: a. CCO/C=C1\C(=O)N(c2ccc(OCC)cc2)C(=O)c2ccccc21
