The sentence suggests that the blank must CONTAIN a word that means 'successor'.

Predecessor and precursor are THINGS that come before something, so they cannot be apt here.

heir and SCION both mean 'successor'.

But; as the article used before the blank is 'a', the correct word here BECOMES 'a scion'. (an heir is the correct usage)

Therefore, the correct answer is option 2.
