Task: Answer the multiple choice question.
Question: Which drug has a -3.373% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a O=C(O)c1oc2ccccc2c1CN1CCN(c2ccccc2)CC1
b CCOc1cc(C(C(=O)NCC2CCCO2)N(C(=O)Cn2nnc3ccccc32)c2ccc(NC(C)=O)cc2)ccc1O
c CCN(C(=O)CN(C)Cc1c(F)cccc1Cl)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
Answer: a. O=C(O)c1oc2ccccc2c1CN1CCN(c2ccccc2)CC1
