Answer:
B-Blew up
Step-by-step explanation:
The other options are incorrect because they do not match the verb tense needed to complete the sentence accurately.
A. "blow up" is the infinitive form of the verb and does not match the past tense context of the sentence.
C. "is blown" is in the present tense, which does not fit with the past tense context of the sentence.
D. "will be blown" is in the future tense and does not match the past tense context of the sentence.
Therefore, the correct option is B. "blew up," which is the past tense form of the verb and aligns with the timeframe indicated in the sentence.
