Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 0.576\% 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 O=C(CCc1nnc(-c2ccccc2)o1)NCc1cc(F)ccc1F
b CCC1(C)Cc2c(sc3c2c(=O)n(C)c2nnc(SCCc4ccccc4)n32)CO1
Answer: a. O=C(CCc1nnc(-c2ccccc2)o1)NCc1cc(F)ccc1F
