Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 5.378\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] CN(C(=O)COC(=O)CCCc1c[nH]c2ccccc12)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
[b] O=C(CNC(=S)N(CCCN1CCOCC1)Cc1cccs1)N1CCOCC1
Answer: b. O=C(CNC(=S)N(CCCN1CCOCC1)Cc1cccs1)N1CCOCC1
