Problem statement: Answer the multiple choice question.
Question: Which drug has a 1.873% 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 other words.
Options:
a) O=C1CC(O)(C(F)F)Oc2ccc3ccccc3c21
b) CC(=O)c1ccc(NC(=O)Nc2cccc(Cl)c2)cc1
c) Cc1cc(C)c(S(=O)(=O)c2c(C)cccc2C)c(OCC(C)C)n1
d) Cn1cc(Cl)nc1C(O)c1ccccc1
Answer: a. O=C1CC(O)(C(F)F)Oc2ccc3ccccc3c21
