Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 1.631\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: CCOC(=O)Cc1c(C)c2c(C)nn(-c3ccccc3)c2oc1=O
b: Cc1ccc(Oc2ncccc2CO)cc1
c: Cc1ccc(OCCCC(=O)Nc2ccc(N3CCOCC3)cc2)c(C)c1
Answer: a. CCOC(=O)Cc1c(C)c2c(C)nn(-c3ccccc3)c2oc1=O
