The correct answer is Option 2: Army Chief's actions being kept hidden from the Prime Minister

After the Kargil conflict, a major controversy emerged in Pakistan regarding whether the military operation had been undertaken without fully informing the then Prime Minister, Nawaz Sharif. There were allegations that the Army Chief and military leadership had kept important details of the operation hidden from the civilian government.

NCERT: In the early part of 1999 several points on the Indian side of the LoC in the Mashkoh, Dras, Kaksar and Batalik areas were occupied by forces claiming to be Mujahideens. Suspecting involvement of the Pakistan Army, Indian forces started reacting to this occupation. This led to a confrontation between the two countries. This is known as the Kargil conflict. This conflict went on during May and June 1999. By 26 July 1999, India had recovered control of many of the lost points. The Kargil conflict drew attention worldwide for the reason that only one year prior to that, both India and Pakistan had attained nuclear capability. However, this conflict remained confined only to the Kargil region. In Pakistan, this conflict has been the source of a major controversy as it was alleged later that the Prime Minister of Pakistan was kept in the dark by the Army Chief. Soon after the conflict, the government of Pakistan was taken over by the Pakistan Army led by the Army Chief, General Parvez Musharraf."
