To combine the two sentences using a past participle, we need to find a verb form that functions as an adjective. Let's analyze the options:

A. "He submitted the completed assignment to his teacher." This sentence combines the two actions, but does not use a past participle.

B. "He completed the assignment and then submitted it to his teacher." This sentence uses the simple past tense to show the completion of the assignment and the subsequent action of submitting it. It does not utilize a past participle.

C. "Before he submitted it to his teacher, he completed his assignment." This sentence creates a chronological order for the actions, but does not involve a past participle.

D. "He submitted the assignment to his teacher after he completed it." Similar to option A, this sentence combines the actions but does not incorporate a past participle.

Based on our analysis, the correct option that combines the sentences using a past participle is B. However, none of the given options actually utilize a past participle to combine the two sentences.
