Which of the following sentences is correct?a.The book’s cover is red. b.The books’ cover is red.c.The books’s covers are red.d.The book’s covers are red

The correct sentence is a. "The book’s cover is red." This sentence is correct because it is referring to one book (singular) and its one cover (also singular).

b. "The books’ cover is red" is incorrect because it is referring to multiple books (plural) but only one cover (singular), which is not possible as each book has its own cover.

c. "The books’s covers are red" is incorrect due to the use of 'books’s'. In English, the possessive form of a plural noun that ends in 's' is formed by simply adding an apostrophe (') after the 's', not 's’s'.

d. "The book’s covers are red" is incorrect because it is referring to one book (singular) but multiple covers (plural). A book typically has only one cover, so the plural form 'covers' should not be used here.
