Respuesta :
The correct answer is B. He, she, it had shrunk. This is because the other examples either don't use the past participle form necessary for the perfect aspect, or they use a different pronoun.
Answer:
B. He, she, it had shrunk.
Explanation:
For the irregular verbs shrink and sink, the simple past tense is "He shrank the material and sank the boat." The past participle is the form of the verb used in the present perfect tense, which shows action completed at the time of speaking: "He has shrunk and has sunk."
