Step 1: Unscramble the Words

First, we unscramble the letters in each option to form meaningful English words:

• A. ONGEAR becomes ORANGE.
• B. NOONI becomes ONION.
• C. ALPEP becomes APPLE.
• D. AUVAG becomes GUAVA.

Step 2: Identify the Common Category and Find the Odd One

Next, we identify the relationship between these words to find the one that does not belong.

• Orange is a fruit.
• Apple is a fruit.
• Guava is a fruit.
• Onion is a vegetable.

The words Orange, Apple, and Guava all belong to the category of fruits. Onion is the only vegetable in the list.

Conclusion

Therefore, ONION (from NOONI) is the odd one out.
