Answer:

Writing is a gerund in this sentence. It is the subject, which is a thing or idea that is doing or being something.  

Answer 2

B. subject

A and D are wrong because there are no objects in the sentence.

C is wrong because, in this sentence, the predicate nominative is a noun phrase, a valuable lifelong skill. Hope this helps.
