Explanation:

- Correct statement: "The minor project put forward by the government is now moving into its third year."

- This indicates progression or transition towards the third year.

- Correct Answer: "is now moving into"

- "is now moving along into":

- "Moving along" suggests steady progress but is redundant with "into."

- Not as clean or concise as option 1.

- "is now moving at":

- Suggests speed or pace but is not appropriate for implying transition into the third year.

- "are now moving into":

- "Are" is incorrect because "the minor project" is singular; it doesn't agree with the subject.
