The correct answer is option 4: 1, 2, and 3.

Let`s break down the conditions necessary for the issue of a writ of quo warranto:

1. The office must be public and must be created by a Statute or by the Constitution itself.

This means that the office in question must be a public office established either by a law or by the Constitution. Private offices or positions created by private entities would not meet this requirement.

2. The office must be a substantive one and not merely the function or employments of a servant at the will and during the pleasure of another.

This condition states that the office should have a substantive role or function, and not be a mere position of employment under someone`s authority. The office-holder should have certain powers and responsibilities associated with the position.

3. There has been a contravention of the Constitution or a Statute or Statutory Instrument in appointing such person to that office.

This condition specifies that there must be a violation of the Constitution, a law, or a statutory instrument in the appointment of the person holding the office. It implies that the appointment was done in a manner that goes against the legal provisions governing such appointments.

Therefore, the correct answer is option 4,
