Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 4.067% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a O=C(CN1C(=O)CSc2ccccc21)N/N=C/c1ccco1
b CC(=O)c1ccc(OCC(O)CN2CCN(Cc3ccc4c(c3)OCO4)CC2)cc1
c COc1ccccc1C(=O)Nc1ccc2c(c1)C(=O)NC2=O
d COc1ccc(-n2c(SCC(=O)Nc3nccs3)nnc2-c2ccoc2C)cc1
Answer: a. O=C(CN1C(=O)CSc2ccccc21)N/N=C/c1ccco1
