Which one of the following statements is correct?

The rank of Second Lieutenant was abolished in the Indian Army following the implementation of the Ajai Vikram Singh (AVS) Cadre Review in 2006. Previously, newly commissioned officers entered as Second Lieutenants, but they are now commissioned directly as Lieutenants. Regarding the other options, the Chief of Army Staff (COAS) is a four-star General, whereas Field Marshal is a five-star honorary rank held for life and is not the standard rank of the COAS. In the military hierarchy, a Lieutenant General is a three-star rank and is senior to a Major General, which is a two-star rank [1]. Finally, the Andaman and Nicobar Command is a tri-service command where officers from the Army, Navy, and Air Force serve together but retain their respective service-specific uniforms and ranks rather than all wearing naval ranks.
