Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 1.644\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a C=CCNc1nc(C)c(CNc2c(C)cc(C)cc2C)nc1C#N
b O=C(COc1ccc(Cl)cc1)N(Cc1ccccc1)c1nc(-c2ccccc2)cs1
Answer: b. O=C(COc1ccc(Cl)cc1)N(Cc1ccccc1)c1nc(-c2ccccc2)cs1
