Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 16.514\% 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] COc1nc(N(C)S(=O)(=O)c2ccc(C)cc2)nc(C)c1Br
[b] CCCn1c2c(c(O)c(C(=O)NC)c1=O)CCCC2
Answer: a. COc1nc(N(C)S(=O)(=O)c2ccc(C)cc2)nc(C)c1Br
