Explanations:The question asks about the mother tongue of Punjab, which refers to the primary language spoken by the majority of the population in the state. The mother tongue is a language that a person learns first and continues to use as their primary means of communication. In the context of Punjab, the mother tongue is Punjabi.
Punjabi is an Indo-Aryan language spoken by the majority of the population in Punjab, both in India and Pakistan. It is the official language of the Indian state of Punjab and is written in the Gurmukhi script. The language has a rich literary tradition and is an essential part of the cultural identity of the region. It is spoken by over 100 million people worldwide, making it one of the most widely spoken languages in the world.
While other languages such as Hindi and Urdu are also spoken in Punjab, they are not the mother tongue of the state. Hindi is widely spoken in northern India and is the official language of the Indian government, but it is not the primary language of Punjab. Urdu, on the other hand, is closely related to Hindi and is spoken by a significant portion of the population, particularly in urban areas, but it is not the mother tongue of Punjab.
Farsi, also known as Persian, is not spoken in Punjab. It is the official language of Iran and is spoken in parts of Afghanistan and Tajikistan. It is not related to the languages spoken in Punjab and is not a part of the linguistic or cultural heritage of the region.
Therefore, the correct answer is that Punjabi is the mother tongue of Punjab. This is based on the linguistic and cultural heritage of the region, where Punjabi is the primary language spoken by the majority of the population and is an essential part of the state's identity.
