Complete answer:
In order to solve this question we need to know more about irrigation, types and farming methods.

Irrigation: It is the supply of water to land or crops to help them to grow, typically by means of channels.
The four methods of irrigation are:
- Surface
- Sprinkle
- Drip
- Subsurface

The main source for irrigation water is groundwater or surface water or municipal water.
Kulhs are local small irrigation canals mainly seen in himachal Pradesh.
They can serve as a rich source of water and means for irrigation for agricultural land.
It is used as a traditional method of irrigation in Himachal Pradesh. It is constructed and maintained by the village community.
It is a surface channel diverting water from natural flowing streams (khuds).
These channels carry glacial melt through gravity from nearby streams to the fields.
The chief food crops cultivated in Agriculture in Himachal Pradesh include wheat, maize, rice, barley, seed-potato, ginger, vegetables, vegetable seeds, mushrooms etc.
Himachal is also known as the ‘apple state of India’ due to its large scale production of fruits.

So, the correct answer is local small irrigation canals.

Note:
Terrace Farming: Terrace farming is the act of creating steps or terraces on mountain slopes to carry out farming.
It is also known as step Farming.
Each level consists of different types of crops being grown.
The advantage is that rains do not wash away the nutrients altogether, but they are pushed down to the lower levels.
