Lok Adalats, or "people`s courts," are judicial and dispute resolution mechanisms in India that focus on compromise and settlement between opposing parties. These are used for a wide variety of cases including civil, criminal and family disputes.

Option 1 suggests that Lok Adalats are held only for disputes with mobile cellular companies. This is incorrect because Lok Adalats deal with more than just one type of dispute.

Option 2 suggests that Lok Adalats are held for both disputes with mobile cellular companies and motor accident cases. While these are types of cases that Lok Adalats handle, it`s not the full extent of their jurisdiction.

Option 3 suggests that Lok Adalats handle motor accident cases only. This is similar to Option 1 where it assumes that Lok Adalats only handle one specific type of case, which is incorrect.

Option 4, which is the correct answer, recognizes that Lok Adalats handle disputes with mobile cellular companies, motor accident cases, and pension cases. It accurately encompasses the diverse types of cases addressed by Lok Adalats.
