Step 1: Recall the three related terms from delegation.
Authority is the formal right to command and take decisions, responsibility is the obligation to carry out the assigned task, and accountability is being answerable for the final outcome.
Step 2: Match the wording in the question.
The question describes the right to command subordinates and act within the scope of one's position, which is a description of a right that flows downward from a higher position.
Step 3: Confirm the term.
Only authority is described as a right that a manager holds over subordinates, responsibility and accountability flow upward instead, and delegation is the act of passing this right down, not the right itself.
Final answer: Option 1, authority.
