Concept:Identify the consonant sound(s) represented by the underlined letters "ph" in the given word.
Explanation:In "upholstery", the letters "ph" are pronounced as the consonant sounds /p/ followed by /h/.
This is because they are not a digraph giving /f/; "p" ends the first syllable and "h" begins the next syllable.
Now check each option:
"phonetics": "ph" gives /f/.
"upheaval": "ph" gives /p/ followed by /h/.
"reception": has no "ph" letters.
"rehearsal": has no "ph" letters.
Only "upheaval" contains the same consonant sounds /p/ and /h/ as "upholstery".
Answer:Option B, "upheaval".
