Explanation
Correct Answer: by
Explanation
• The preposition by is used to indicate the degree, extent, or amount of a change, increase, or decrease.
• Verbs showing movement or change (such as go up, increase, rise, decrease, or fall) are followed by by when specifying a margin or percentage.
• Example: Fuel prices rose by two rupees this week.
Quick Tip: Use by to express the extent or margin of variation (e.g., increased by 10%, won by two runs).
