Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 4.845\% 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. CCCCC(=O)N/N=C/c1c(O)n(CCc2ccc(OC)c(OC)c2)c(=O)[nH]c1=O
b. CN(C)S(=O)(=O)c1ccc(-c2csc(-c3cccnc3)n2)cc1
Answer: a. CCCCC(=O)N/N=C/c1c(O)n(CCc2ccc(OC)c(OC)c2)c(=O)[nH]c1=O
