Final answer:
The syllable with no consonant blend is known as an open syllable, where the vowel typically has a long sound. The correct option is A.
Step-by-step explanation:
When there is no consonant blend in a syllable, the syllable is referred to as an open syllable. An open syllable ends in a vowel sound and the vowel is typically long.
For example, in the word 'go', there is no consonant following the 'o', making it an open syllable with a long 'o' sound. In contrast, a closed syllable ends in a consonant and the vowel sound is usually short. The correct option is A.
