SRAS Curve describes:

SRAS Curve describes:

• A. The short-run relationship between the aggregate price level and the quantity of aggregate output supplied when some production costs are fixed.
• B. A graphical representation of the relationship between the aggregate price level and the quantity of aggregate output supplied in the short run, when many production costs are fixed.
• C. A positive slope curve describing the long-run relation between price level and output when all prices are flexible.
• D. A horizontal curve reflecting supply when costs adjust immediately.

Answer: (B)

The main idea is that the short-run aggregate supply (SRAS) shows how much output firms are willing to produce in the short run as the overall price level changes, given that many production costs don’t adjust immediately. In the short run, wages and several input costs are sticky or fixed, so when the price level rises, firms can boost profitability without instantly raising those fixed costs. That incentive leads them to produce more, creating an upward-sloping relationship between the price level and the quantity of output supplied. That’s why the description focusing on a short-run relationship where many production costs are fixed best captures what SRAS represents. The long-run relationship, by contrast, involves all prices being flexible and is vertical at potential output. A horizontal curve would imply costs adjust immediately, which isn’t the typical short-run behavior. Saying only that some costs are fixed is less precise about the broader short-run dynamics.
