A Correct answer
Explanation

'On the sly' means secretly, discreetly, or in a stealthy manner - doing something while trying to avoid detection. When someone deals in smuggled items 'on the sly,' they're conducting this illegal trade secretly. Option A 'on the sly' is the correct idiomatic expression; 'slyly' is just an adverb, not the idiom itself.
