  1. Jennifer is Ten

  2. Jennifer is five

  3. Jennifer is Twenty

  4. Jennifer is fifteen


Correct Option: D

AI Explanation

To answer this question, we need to consider the given system where each person is assigned a number of points based on the number of syllables in their name.

Given: Susan = 10 points (2 syllables) Arabella = 20 points (3 syllables) Jim = 5 points (1 syllable) Neal = 5 points (1 syllable) Richard = 10 points (2 syllables)

Now, let's consider Jennifer.

Jennifer has 3 syllables in her name, so according to the given system, she would receive 3 points.

Therefore, the correct answer is:

D) Jennifer is fifteen - This option is incorrect because Jennifer would receive 3 points, not 15 points.
