To which of the following does Oscar Wilde compare his poems?

a. gardens

b. love

c. flower petals

I would say that Oscar Wilde compares his poems to C. flower petals.

This is what he says in his poem, 'To My Wife:'

For if of these fallen petals One to you seem fair,

Love will waft it till it settles On your hair.

Here, you can see that he uses the word 'fallen petals' to refer to his poems, which he hopes his loved one will like.

Oscar Wilde compares his poems to gardens.
