The correct answer is: b) Eucalyptus.
Eucalyptus is not commonly found in Punjab because it is not a native tree to the region. It is native to Australia and was introduced to Punjab in the 19th century. Eucalyptus trees are fast-growing and can tolerate a wide range of climates, but they are not well-suited to the dry, hot climate of Punjab. They also have a tendency to crowd out native plants and can damage the soil. As a result, eucalyptus trees are not widely planted in Punjab and are not considered to be a common tree in the region.
Mango, sal, and mulberry are all native trees to Punjab and are commonly found in the region. Mango trees are known for their delicious fruit, which is a popular food in Punjab. Sal trees are a type of hardwood tree that is used to make furniture and other wood products. Mulberry trees are known for their leaves, which are used to feed silkworms.
In conclusion, the correct answer to the question “Which of these trees is NOT commonly found in Punjab?” is b) Eucalyptus. Eucalyptus is not a native tree to Punjab and is not well-suited to the dry, hot climate of the region. As a result, eucalyptus trees are not widely planted in Punjab and are not considered to be a common tree in the region.
