Answer:
B. The time between stressed words is always different.
Explanation:
Sentence stress is referred to as the stress or emphasis on some particular words in a sentence providing an accent to the language and adds to the rhythm and makes it fluent to read.
The sentence stress consists of three rules that include:
1. Content words are stressed. (sell, car, big, why, can't, etc.)
2. The structure words are unstressed. (we, on, a, and, do, etc.)
3. The time between stressed words will always be the same.
Thus, the untrue statement is B i.e. the time between stressed words is always different.
