With reference to 'Changpa' community of India, consider the following statements : 1. They live mainly in the State of Uttarakhand. 2. They rear the Pashmina goats that yield a fine wool. 3. They are kept in the category of Scheduled Tribes. Which of the statements given above is/are correct?

Lists northern states (Jammu & Kashmir, Himachal Pradesh, Uttarakhand, etc.) where Indo‑Aryan tribes are presently found, indicating tribal/ethnic groups are distributed across multiple Himalayan states.

A student could compare the known high‑altitude tribal groups (like Changpa if remembered as trans‑Himalayan pastoralists) against this list to judge whether Uttarakhand is a primary location or one of several possible states.

Describes Uttarakhand as a state that touches the India–China (Tibet) middle sector along a Himalayan watershed, implying it includes high mountain border areas.

One could use a map of Changpa habitat (usually in trans‑Himalayan border zones) and check whether those areas fall within Uttarakhand's Himalayan border described here.

Notes seasonal migration patterns to mountain states (Jammu & Kashmir, Himachal Pradesh, Uttarakhand, Sikkim), suggesting pastoral or seasonal high‑altitude use of these states.

If Changpa are a pastoral/seasonally mobile group, this pattern suggests they might be present in several Himalayan states; a student could investigate which specific states host such pastoral migration.

Gives an example of a tribal community (Tharus) concentrated in parts of Uttarakhand and neighboring Uttar Pradesh, showing tribes can be regionally concentrated within specific tehsils/districts.

A student could use this example to reason that being a tribal group does not guarantee statewide predominance—one should check district/tehsil level distribution for Changpa rather than assume Uttarakhand-wide majority.

States that scheduled tribes are mainly concentrated in rural and specific ecological areas across states, implying tribal populations are spatially non‑uniform.

A student could combine this rule with knowledge of Changpa ecology (if known as trans‑Himalayan/pastoral) to narrow likely states that contain appropriate rural high‑altitude habitats, rather than assuming Uttarakhand alone.
