The police explained that all the aggrieved persons should seek … in the court of law.

Step 1: Analyze the question The sentence is: "The police explained that all the aggrieved persons should seek ___ in the court of law." We need a word that fits with "seek ... in the court of law" and relates to people who feel wronged ("aggrieved").

Step 2: Explain the concept

• Redress (noun) means compensation or remedy for a wrong or grievance. We "seek redress" when we have been wronged.
• Litigation means the process of taking legal action. It is the process itself, and we usually "go into litigation" or "engage in litigation" rather than "seek litigation in court."
• Address means a speech or a location. It does not fit here.
• Restoration means returning something to its original state. It is too general and is not a standard legal collocation.

Step 3: Work through the options

• "Seek redress" is a very common collocation. It means to look for a remedy for a wrong.
• "Aggrieved persons" are people who have suffered an injustice, so they would seek redress.
• "In the court of law" shows where the remedy is sought, and redress fits that perfectly.
• "Seek litigation in the court" is redundant, because litigation already means going to court.

Step 4: Answer The correct option is A. redress.

Tip: Link the words aggrieved and redress together, since both deal with a wrong and its remedy. Remember the phrase "seek redress" and you will recognize it in many exam questions.
