Spelling – Identify the single misspelled word among options A–D (choose exactly one; ignore “All correct”). A) Benificial B) Regular C) Despise D) Deprave

Introduction / Context:
Words ending in “-ficial” often derive from the Latin “facere/fact-” (to make). The correct English mapping after “bene-” (good) is “beneficial”, not “benificial”. The vowel immediately after “ben-” is “e” reflecting “bene-”.

Given Data / Assumptions:

• A: Benificial – intended “beneficial”.
• B: Regular – correct.
• C: Despise – correct.
• D: Deprave – correct.

Concept / Approach:
Prefix “bene-” (good) + base related to “facere” gives “benefit/beneficial” where the vowel is “e”. The incorrect “benificial” swaps “e” for “i” after the prefix and breaks the known family: benefit, beneficiary, beneficial.

Step-by-Step Solution:
1) Recall family: benefit → beneficial.2) Compare letters: be-ne-fi-cial is correct; “be-ni-fi-cial” is wrong.3) Validate other choices against common usage: regular, despise, deprave—standard forms.4) Choose A as the lone misspelling.

Verification / Alternative check:
Derivatives like “beneficiary” again show “bene-”, never “beni-”.

Why Other Options Are Wrong:

• Regular: correct; “regullar/reguler” are wrong.
• Despise: correct; not “despice”.
• Deprave: correct; beware confusion with “deprive”.

Common Pitfalls:
Mixing up “beneficial” and “beneficiary”; replacing the second “e” with “i” due to pronunciation influences.

Final Answer:
Benificial
