Step 1: Read the question.
Who are the subjects of International Law today?
Step 2: Recall the old view.
Earlier, only sovereign states were considered subjects of International Law.
Step 3: Note the modern change.
Now international organisations like the UN have legal personality, and individuals also have rights and duties, for example human rights and liability for international crimes.
Step 4: Combine the categories.
So modern subjects include states, international organisations, and individuals.
Step 5: Eliminate the others.
Options that mention only states, or only organisations, or only states and organisations leave out individuals, so they are incomplete.
Step 6: Conclude.
The subjects are states, international organisations, and individuals.
Answer: States, International Organizations and Individuals
