Task: Answer the multiple choice question.
Question: Which drug has a -14.273% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] O=C(c1cccc(NS(=O)(=O)c2ccc(F)c(F)c2)c1)N1CCN(C(c2ccccc2)c2ccccc2)CC1
[b] COc1ccc(N2CCN(C(=O)CS(=O)Cc3nc(-c4ccc(OC)c(OC)c4)oc3C)CC2)cc1
[c] OCCN1CCN(c2nnc(-c3ccccc3)c3ccccc23)CC1
Answer: a. O=C(c1cccc(NS(=O)(=O)c2ccc(F)c(F)c2)c1)N1CCN(C(c2ccccc2)c2ccccc2)CC1
