Problem statement: Answer the multiple choice question.
Question: Which drug has a 6.681\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) O=C(CSc1nnc(-c2ccco2)n1-c1ccccc1)N1CCOCC1
b) O=C1C(c2ccncc2)=C(O)c2ccccc21
c) CC(C)C(C(=O)Nc1ccc(S(=O)(=O)N2CCOCC2)cc1)N1C(=O)c2ccccc2C1=O
Answer: b. O=C1C(c2ccncc2)=C(O)c2ccccc21
