Himachal Pradesh, Assam, Maharashtra, and Karnataka having the lowest net sown area under irrigation Whereas Punjab and Haryana have the highest net sown area.

The maximum part of the total irrigated area of the country by canals is in Uttar Pradesh. Other major states where irrigation is done by canals are Madhya Pradesh, Andhra Pradesh, Haryana, Punjab and Bihar.

• Whale hunting is carried out in the oceans. 

Fishing in the oceans is typically a very multifaceted action, you can imagine the high concentration hurricane usually present in the ocean, it may be very difficult for the fishermen to cop up the situation, this is because the boats used for fishing may be influenced by the storm to a point of leasing water into the boats and finally making the boats to overturn. 

Fishing is a major activity that can selectively remove a large portion of animal populations and also considerably change tropic connections. Fishing gear that drags the bottom at times, such as bottom-trawls, pots, and loglines, can alter marine habitats, especially benthic or reef habitats. 

Because fish populations change naturally, sometimes by orders of magnitude, separating the effects of fishing from natural and environmental unpredictability is difficult.

Thus, the correct option is D.

• Inland fisheries are generally characterized by small-scale/household-based activities. Participation in fisheries is high and the bulk of the catch is consumed locally.

Marine fisheries, as well as fisheries in large lakes, depend on the coastal region in a variety of ways. Most capture fisheries are base on coastal stocks; others develop offshore stock which spends part of their life in inshore waters, e.g., in a nursery school or feed area. 

Fish stocks also rely on the main efficiency in the coastal area as an important part of the food chain. Coastal aquaculture is also greatly charged on the coastal area for liberty and wealth. 

This dependence of the marine fisheries segment on the coastal area makes it mainly at risk to activities which result in coastal environmental change which may have major impacts on the sector. At the same time, the fisheries sector can affect other coastal activities.

Thus, the correct option is A.
