The type of soil primarily found in Punjab is considered young and undeveloped as it originated from:

The correct answer is: c) Recent river deposits.

Punjab is a state in northwestern India and eastern Pakistan. The soil in Punjab is considered young and undeveloped because it originated from recent river deposits. These deposits are made up of sediments that have been carried down by rivers from the Himalayas. The sediments are mostly sand and silt, and they are very fertile.

The other options are incorrect because:

• Volcanic eruptions do not occur in Punjab.
• Weathering of ancient rocks can create soil, but it takes a long time. The soil in Punjab is not that old.
• Metamorphic processes do not create soil. They change existing rocks into new types of rocks.

I hope this helps! Let me know if you have any other questions.
