• A. Burn rate is the rate of cash expenditure per month; manage with runway planning, expense control, and fundraising.
• B. Burn rate is the total investment; manage by increasing costs.
• C. Burn rate is monthly revenue; manage by cutting prices.
• D. Burn rate is the number of burnable assets; manage by liquidation.

Answer: (A)

Burn rate is how quickly a startup is spending cash each month, which shows how fast you’re consuming your available runway. Knowing this helps founders plan how long you can operate before needing more money and what actions are needed to extend that period.

Founders manage cash burn by focusing on runway planning, expense control, and fundraising. Practically, this means tracking monthly cash outflows (and, if possible, net burn versus revenue), building a realistic budget, and identifying nonessential costs to cut or push out. It also involves prioritizing spend that drives growth or revenue, negotiating better terms with vendors, and delaying hiring or large investments when speed isn’t essential. When burn is higher than desired, you look to extend runway by increasing cash on hand (fundraising) or accelerating revenue (pricing, sales efforts, product milestones). Keeping a close forecast and revising plans as numbers change helps maintain liquidity and reduces the risk of a cash crunch.

To connect the idea to a simple rule of thumb: runway equals cash on hand divided by net burn per month. If you have one million in the bank and your net burn is 100,000 per month, your runway is about ten months. The focus is on managing that burn rate through disciplined budgeting, cost control, and timely fundraising or revenue-generating moves.

The other descriptions mix up what burn rate measures or how it’s managed: it’s not total investment, it’s not monthly revenue, and it’s not about assets to liquidate. Burn rate specifically tracks cash consumption and how to extend the time you have to reach the next milestone or funding round.
