Answer :
Option “D” is the correct option. “I shall be all that I am
and more” is a perfect sentence that has a verb phrase. Actually any verb
phrase should technically consist of a phrase that has more than one verb of
different types. In regards to the options given, we can see that only in case
of option “D” there is a phrase having two verbs and they are “shall and “be”.
The other given sentences normally consist of a single verb and so cannot be
considered a verb phrase.
