The correct answer is C. Samuel Clemens was born in 1835, and he is better known by the pen name Mark Twain

Explanation:

In grammar, the word coordination refers to linking two or more elements that have the same importance with coordinating words such as but, or, and. On the other hand, faulty coordination occurs when two ideas that do not have the same importance or belong to the same category are linked by using a coordinating conjunction or when there are grammatical issues in the use of coordinating words. Considering this, the sentence that is an example of faulty coordination is "Samuel Clemens was born in 1835, and he is better known by the pen name Mark Twain" because in this case two ideas that do not have the same importance and are unequal are linked with the coordinating conjunction "and" which creates a confusing construction and is an example of faulty coordination.
