When is the supply more likely to be inelastic?Option     When the price increases     When there are many firms     When factors of production are mobile     When marginal costs grow slowly

The supply is more likely to be inelastic when marginal costs grow slowly.

Here's why:

1. Inelastic supply refers to a situation where the quantity supplied by producers does not change (or changes very little) in response to changes in price.

2. When marginal costs grow slowly, it means that the cost of producing additional units of a good or service does not increase significantly.

3. Therefore, even if the price of the good or service decreases, producers can still afford to supply the same quantity because their costs have not increased significantly.

4. Conversely, if the price increases, producers can still supply the same quantity without incurring significantly higher costs.

5. This makes the supply inelastic, as the quantity supplied does not change significantly in response to changes in price.

The other options do not necessarily lead to inelastic supply. For example, having many firms in the market or having mobile factors of production can lead to more competition and more elastic supply, as firms can easily enter or exit the market in response to changes in price. Similarly, an increase in price does not necessarily lead to inelastic supply, as it depends on how producers respond to the price change.
