Answer:
B. re/act
C. sci/ence
Explanation:
In oral English, most vowel pairs relate to a single vowel sound, such as toe, lie, etc. In other vowel pairs, usually in multisyllabic words, each vowel is sounded in each pair thereby creating a v/v syllable (a vowel/vowel) syllable.
From the list option given, the words that contain a v/v open syllable pattern are re/act and sci/ence.
