Their tracks over India are mainly determined by the position of ITCZ, which is generally termed as monsoon trough. As the axis of the monsoon trough oscillates, the tracks of these depressions also vary.

The UN Arms Trade Treaty (ATT) has the ambitious aim of responding to international concern that the $70 billion a year trade in conventional weapons leaves a trail of atrocities in its wake.
1. The treaty calls for the international sale of weapons to be linked to the human rights records of buyers.
2. It requires countries to establish regulations for selling conventional weapons.
3. It calls for potential arms deals to be evaluated in order to determine whether they might enable buyers to carry out genocide, crimes against humanity, or war crimes.
4. The treaty also seeks to prevent conventional military weapons from falling into the hands of terrorists or organized criminal groups, and to stop deals that would violate UN arms embargoes.

The treaty does not regulate the domestic sale or use of weapons in any country. It also recognizes the legitimacy of the arms trade to enable states to provide for their own security
Conventional weapons covered by the UN Arms Trade Treaty include tanks and other armored combat vehicles, artillery, attack helicopters, naval warships, missiles and missile launchers, and small arms.
It also establishes common international standards for the regulation of the international trade in ammunition, weapons parts, and arms components.

2015 UPSC Prelims Question
In a welfare State, the functions of the State are not only the defence of the country or administration of justice or maintaining law and order but it extends to regulating and controlling the activities of the people in almost every sphere—educational, commercial, social, economic, political and even marital.
DPSP thus promotes the ideal of a welfare state as it guides the state in making policies for the socio-economic well being of the people of India.
Preamble, option A, will NOT be the answer because it simply lists the socio-economic objectives of Indian society. It does not tell us who will design or execute policies based on the objectives.
