Explanation

Let's analyze the statements regarding the Agni-IV Missile: **It is a surface-to-surface missile.** This statement is **correct**. The Agni series of missiles are indeed strategic ballistic missiles designed for surface-to-surface delivery. **It is fuelled by liquid propellant only.** This statement is **incorrect**. Agni-IV is a two-stage ballistic missile that uses solid propellants for both stages. Solid propellants offer advantages like easier storage, quicker launch times, and higher reliability compared to liquid propellants, which are common in many modern ballistic missiles. **It can deliver one-tonne nuclear warheads about 7500 km away.** This statement is **incorrect**. The range of the Agni-IV missile is approximately 4,000 kilometers. The range of around 7,500 km (or higher) is associated with the Agni-V missile, which is a longer-range Intercontinental Ballistic Missile (ICBM) in the Agni series. Therefore, only statement 1 is correct.
