Answer :
A literary text can be written in different forms, which include prose and verse. Therefore, the correct answer to the question is:
a. en prosa y en verso.
Prose refers to writing that is structured in sentences and paragraphs, without a specific metrical structure like poetry. It is the most common form of writing in literature and can be found in novels, short stories, essays, and more.
On the other hand, verse refers to writing that has a specific metrical structure, such as poems. Poetry uses line breaks and stanzas to create rhythm and often includes rhyme and other poetic devices to convey meaning in a more condensed and structured form.
So, a literary text can indeed be written in prose, like a novel, or in verse, like a poem, showing the versatility and richness of literary expression.
