Problem statement: Answer the multiple choice question.
Query: Which drug has a 6.474\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
(a) O=C(NOC(=O)c1ccccc1F)c1ccc(OC(F)F)cc1
(b) COP(=O)(Cc1ccc(C#N)o1)OC
(c) CCCn1c2ccccc2c2nnc(SCC(=O)OC)nc21
Answer: a. O=C(NOC(=O)c1ccccc1F)c1ccc(OC(F)F)cc1
