Hint: The given sentence is referring to two actions. The first action is in the past continuous tense while the second act is in the simple past tense. The correct option for the blanks can be chosen by verifying the given options with the syntax for each tense.

Complete answer:
To solve this question we need to understand simple past and past continuous tense. Simple past is a verb tense that is used to show an action that was completed at a specific time in the past. Past continuous tense on the other hand is used to show an ongoing past action that was happening at a specific time in the past or when two ongoing actions were happening at the same time.
The simple past is formed using the verb + ed and the past continuous tense is formed using was/were + past participle.
Let us look at the given options and see which option follows these forms.
We can see that the only options that have words in the given form is option ‘B’ and option ‘D’.
From this, option ‘D’ is incorrect as simple past needs to be used for the second blank and past continuous needs to be used for the first blank, but here it is in reverse.
So, the correct answer is “Option B”.

Note:
To answer such questions with ease it is necessary to know the various types of tenses, its format, and usage. It is advisable to first try and understand the sentence structure and the possible answers, before taking a look at the options to avoid confusion.
