The correct answer is (d). The death of plaintiff or defendant will not cause the suit to abate if the right to sue survives.
A suit is a legal proceeding in which a plaintiff (the person who is bringing the suit) asks a court to order the defendant (the person who is being sued) to do something or to pay money. If the plaintiff dies, the suit will abate (be stopped) unless the plaintiff’s personal representative (the person who is appointed to manage the plaintiff’s estate) or another person with standing to sue (such as the plaintiff’s heirs) takes over the suit. Similarly, if the defendant dies, the suit will abate unless the defendant’s executor or administrator (the person who is appointed to manage the defendant’s estate) or another person with standing to be sued takes over the suit.
However, there are some exceptions to this rule. For example, if the suit is for personal injury or wrongful death, the suit may continue even if the plaintiff or defendant dies. Additionally, if the suit is for breach of contract, the suit may continue if the contract contains a clause that allows the contract to be assigned to another person.
In general, the death of a party to a suit will not cause the suit to abate if the right to sue survives. However, there are some exceptions to this rule, and it is important to consult with an attorney to determine whether the death of a party will affect your case.
