Of course? — Choose the option that has the same consonant sound as the one represented by the underlined…

The question lost its underlined letters in formatting, and "Of course" is the clue. The underlined part is almost certainly "f" in "Of" (the word is likely "Of course"), so we are matching the consonant sound in "of".

Step 1: Analyze the question We need the consonant sound of the underlined letters. In "of", the letter "f" is pronounced /v/ (the word is /ɒv/ or /əv/), not /f/. This is a well-known trick in JAMB phonetics questions.

Step 2: Explain the concept In English, the letter "f" is usually pronounced /f/ (as in "fan"), but in the word "of" it is voiced as /v/. So we must look for an option containing the /v/ sound.

Step 3: Check each option

• A. plough /plaʊ/: the "gh" is silent, so there is no /v/ or /f/ sound here.
• B. dough /dəʊ/: the "gh" is silent again.
• C. over /ˈəʊvə/: the "v" is pronounced /v/. This matches the sound in "of".
• D. orphan /ˈɔːfən/: the "ph" is pronounced /f/, which is voiceless. This does not match /v/.

Step 4: Answer The correct option is C. over, because the "v" in "over" has the same /v/ sound as the "f" in "of".

Tip: Memorize that "of" is the one common word where "f" sounds like /v/. When you see "of" in a consonant-sound question, look for a /v/ word. Also remember that "gh" in "plough" and "dough" is silent, while "ph" always gives /f/ (a voiceless sound), so these are distractors.

Note: because the underlined letters did not show in your question, I based this on the phrase "Of course". If your original had a different part underlined, send it and I will recheck.
