a. coal was less wasteful than steam power.
b. coal was more plentiful than steam.
c. coal provided a greater concentration of energy than steam.
d. coal was more readily available than steam.

Explanation:

Coal has a higher energy density compared to steam. This means that a given amount of coal can produce more energy. During the Industrial Revolution, this greater concentration of energy from coal allowed for more powerful machinery and increased productivity in factories and industries.
