The error in consistency and parallelism can be identified by looking at the structure and grammar of the given sentences. Consistency refers to maintaining a uniform style or pattern throughout a sentence or paragraph, while parallelism refers to using similar grammatical structures for similar ideas.

Let's analyze the given options to find the correct answer in terms of consistency and parallelism:

A. "Actually, the pineapple was a symbol of hospitality."
This sentence does not have any noticeable inconsistency or lack of parallelism.

B. "Everything that King Midas touched turned to gold, including his food and water."
This sentence does not have any noticeable inconsistency or lack of parallelism.

C. "The farmer butchered the pig he had raised on a table behind the barn."
This sentence does not have any noticeable inconsistency or lack of parallelism.

D. "Now remembered as the architect who designed St. Paul's Cathedral, Christopher Wren was also a professor of astronomy and a mathematician."
In this sentence, there is a lack of parallelism between the introductory clause ("Now remembered as the architect who designed St. Paul's Cathedral") and the following clauses ("Christopher Wren was also a professor of astronomy and a mathematician"). To achieve parallelism, the sentence should be revised as follows: "Now remembered as the architect who designed St. Paul's Cathedral, Christopher Wren was also known as a professor of astronomy and a mathematician."

Therefore, the correct answer is C. "The farmer butchered the pig he had raised on a table behind the barn."
