Solution:Philip Sidney's 'The Arcadia' was influenced by 'The Spanish Romance of Montemayor'. It is a prose romance. It exists in two versions: the first, completed by 1581, it is known as the Old Arcadia; the second version, now known as the New Arcadia.
Another 'Arcadia' is a series of verse eclogues connected by prose narrative, published in 1504 by Sannazar, occupied with the loves, laments and other doings of various shepherds in Arcadia, while Arcadia is a district in the central Peloponnese, through which Virgil's 'Ecologues' became the traditional location of the idealized world of pastoral.
Hence, option (a) will be correct answer.
