B Correct answer
Explanation

The sentence describes improving vocabulary size. 'Increase' is the correct verb meaning to make something greater in amount or degree. 'Amass' means to gather together over time but is less common for abstract skills, 'collect' and 'gather' are similar to each other and more about physical objects - increase is the most natural verb for vocabulary improvement.
