Final answer:
The appropriate word to complete the sentence is 'nuestra' which means 'our' in English.
Step-by-step explanation:
The subject of this question is Spanish. The sentence is asking for the appropriate word to complete the sentence.
The word that properly completes the sentence is nuestra, which means 'our' in English. The sentence would then translate to 'You have to give us your hand.'
Other options are not grammatically correct in this context. For example, 'Ola' means 'wave,' 'O tu' means 'or you,' 'Omi' does not have a meaning in Spanish, and 'O' means 'or.' So, the correct answer is nuestra.
