Concept:The sound of the underlined
f in "fly" is the consonant sound
/f/.
We need to find the word that contains the same
/f/ sound.
Explanation:In "fly", the letter
f gives the sound
/f/.
Option A, "though", has a silent
gh and gives no
/f/ sound.
Option B, "dough", also has a silent
gh and does not give
/f/.
Option C, "revive", has the letter
v, which gives
/v/, not
/f/.
Option D, "tough", is pronounced as
/tʌf/.
Here the letters
gh together produce the
/f/ sound.
So "tough" has the same consonant sound as the underlined
f in "fly".
Answer:D. tough
