Goods or services in standard-cycle markets reflect: a. numerous first-mover advantages. b. organizations that serve a mass market. c. an inability to sustain a competitive advantage except for brief periods of time. d. competitive advantages that are shielded from imitation.

Option b.

Explanation:

In standard cycle, competitive actions are designed to serve large market shares, to gain customer loyalty and to control the firm's operations which in turn provide the same positive experience to customers.

Goods or services in standard-cycle markets reflect organizations that serve a mass market.

Standard-cycle markets refer to the markets where the firm's competitive advantages are shielded from imitation such that those advantages can be sustained longer but for a shorter period.

These advantages can be sustained for longer period in a slow-cycle market  than in fast-cycle markets.

Competitive advantages are sustainable in slow-cycle as these are shielded from imitation for longer periods of time such that imitation is costly.

Option b. is correct
