Which of the following does not have /i:/ sound?

Correct option is D

The word "pretty" does not have the /i:/ sound. Instead, it contains the /ɪ/ sound, a shorter and less tense vowel. In contrast, "week," "bean," and "deep" all have the /i:/ sound, a long, tense vowel characterized by a higher tongue position.
Information Booster:
1. /i:/: A long vowel sound as in "see" or "green."
2. /ɪ/: A short vowel sound as in "sit" or "pretty."
3. Tense and Lax Vowels: /i:/ is tense, while /ɪ/ is lax.
4. Examples of /i:/: "meet," "beach," "peace."
5. Dialectal Variation: /i:/ may merge with /ɪ/ in some accents, e.g., Cockney English.
