b. No sooner had I woken up than I brushed my teeth.
c. No sooner I woke up than I brushed my teeth.
d. No sooner did I wake up than I brush my teeth.

Answer 1

Hint: ‘No sooner than’ refers to an action that happens immediately after another action.
Complete answer:
As given in the hint, ‘no sooner than’ is used to indicate the second action that takes place right after the first action.
‘No sooner than’ is generally used with the past perfect tense of a verb.
Example- No sooner than + had + 3rd form of the verb
No sooner had she started her walk than it started to snow. Here, we can understand that the first action of walking was immediately followed by the action of snowing.
In the given question: We can conclude that X began the first action of waking up, followed by the second action of brushing his teeth.
Now, let’s examine the given options:
We cannot use the simple past tense form of the verb with ‘no sooner than’. Hence, it is an incorrect option.

We have used the past perfect tense form of the verb with ‘no sooner than’. Hence, it is the correct option.

The composition of the sentence is grammatically inaccurate. Hence, it is an incorrect option.
The formation of the sentence is inappropriate. Hence, it is an incorrect option.
The correct answer is Option ‘b’.
Note: We always place ‘no sooner’ at the beginning of the sentence, while the auxiliary verb and main verb follow ‘than’.
