The district woken up to a thick blanket of snow this morning as the winter entered its most bitter phase.

Correct option is D

The correct substitution of the highlighted words is (d) woke up to a.
Explanation:
· The verb “woken” is the past participle form and must be used with an auxiliary verb (like has, had, or was), which is missing here.
· Since the sentence is in simple past tense ("this morning", "entered"), the correct form is “woke up”, which is the simple past of “wake up.”
· The article “a” is appropriate before “thick blanket.”
Grammatical rule used:
· Use simple past (woke up) for completed actions in the past.
· Avoid using past participle (woken) without a helping verb.
Example:
✅ She woke up to the sound of birds.
❌ She woken up to the sound of birds.
