Which of the following words is spelled correctly?

The word "and" is a conjunction that joins two related actions.

The correct choice isChoice B: “The boys and girl visit my house.”

This sentence is correctly punctuated and uses the correct verb form to agree with the plural subject “boys and girl”.

There is a mismatch in verb tense and subject. The sentence starts with "if a person wants", and then shifts to "you have to". For consistency, it should either stay with "a person" or use "you" throughout.

• A corrected version could be: "If a person wants to get ahead in life, they have to be willing to work for it."
• Or: "If you want to get ahead in life, you have to be willing to work for it."

This is a valid issue, so this choice is correct.

The word "Consequently" should be used to show cause and effect as it indicates a logical result or consequence of a previous action or event.

I walked all three dogs around the park this morning

The word "crucial" is the only correct spelling and fits the context of the sentence.
