B. Consequently, the house which is known for its wonderful architecture is infested with mice, cockroaches and alligators.
C. Consequently, the house, which is known for its wonderful architecture, is infested with mice, cockroaches and alligators.
D. Consequently the house which is known for its wonderful architecture, is infested with mice, cockroaches and alligators.

Sentences use commas correctly: C) Consequently, the house, which is known for its wonderful architecture, is infested with mice, cockroaches, and alligators.

Explanation:

The correct usage of commas is crucial for maintaining clarity and proper punctuation. In this case, option c is the correct choice. It appropriately places commas to set off the non-essential clause "which is known for its wonderful architecture."

Additionally, commas are used to separate items in the list "mice, cockroaches, and alligators," ensuring proper structure. Option a lacks a comma after "Consequently," leading to a less organized sentence. Option b incorrectly omits the second comma after the introductory clause. Option d lacks necessary commas, resulting in a sentence that lacks clarity and proper punctuation.

Hence the correct answer is C) Consequently, the house, which is known for its wonderful architecture, is infested with mice, cockroaches, and alligators.
