Mark the word whose underlined part from the other three in pronunciation: beaches, services, messages, techniques

Detailed solution:

A. beaches /biːtʃɪz/

B. services /ˈsɜːvɪsɪz/

C. messages /ˈmesɪdʒɪz/

D. techniques /tekˈniːk/

Rule:

There are 3 ways to pronounce the last consonant “s/es”:

– /s/: When a word ends in soundless consonants /p/, k/, /f/, /ð/, /t/

– /ɪz/: When the word ends with the sounds /s/, /ʃ/, /tʃ/, /z/, /ʒ/, /dʒ/ (usually ending in the letters ce, x) , z, sh, ch, s, ge, ss)

– /z/: When the word ends with vowels and the remaining consonants.

Option D has the final pronunciation /k/ (e mute), adding “s” makes “es” read as /s/, the remaining options are /ɪz/.
