To identify the error in capitalization in the given sentence, you need to have a basic understanding of grammar rules for capitalizing titles. In general, the first and last words of a title should be capitalized, along with all nouns, pronouns, adjectives, verbs, adverbs, and subordinating conjunctions (such as "of," "in," "on," etc.).

Let's analyze each option to find the correct answer:

A. "Progress" - This option suggests that the error lies with the title "Pilgrim's progress." Since "progress" is a noun and falls within the rules of capitalizing titles, this option is incorrect.

B. "pilgrim's" - This option suggests that the error lies with "pilgrim's." The possessive noun "pilgrim's" should only be capitalized if it is the first word of the title. However, since "Pilgrim's progress" is the title of a book, "pilgrim's" should not be capitalized. This option corrects the error.

C. "john" - This option suggests that the error lies with the name "John." Proper nouns like names should always be capitalized, so "John" is correctly capitalized. Therefore, this option is incorrect.

D. "Books" - This option suggests that the error lies with the word "Books." Since the general rule is to capitalize all nouns in a title, "Books" is correctly capitalized. Therefore, this option is incorrect.

Based on the analysis, the correct answer is B. "pilgrim's," as it correctly addresses the error in capitalization by not capitalizing the possessive noun "pilgrim's" in the title "Pilgrim's progress."
