Task: Answer the multiple choice question.
Question: Which drug has a 16.744\% 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] O=C(NN1c2ccccc2CCc2ccccc21)c1ccccc1Br
[b] CN(Cc1cn(-c2ccccc2)nc1-c1cc2ccccc2o1)C(=O)CCC(=O)O
[c] CCOC(=O)N1CCN(C(=O)CCN2C(=O)/C(=C\c3cccc(OC)c3)SC2=S)CC1
[d] O=C(CCn1cccc1)NCc1ccc2c(c1)OCO2
Answer: a. O=C(NN1c2ccccc2CCc2ccccc21)c1ccccc1Br
