Many Telecom Firms Began Digging Up the Ground and Laying

Many telecom firms began digging up the ground and laying webs of fiberglass to meet the growing demand for Internet connectivity. However, rivals and startups began to imitate these firms and soon these new assets were not so rare and each day they seemed to be less valuable. It can be inferred from this example that:

A) resource-based thinking can help avoid the trap of carelessly entering markets simply because growth is spotted.
B) the telecommunications market is only big enough to support one or two major players.
C) the immense scale advantages enjoyed by major firms can help them fight off competition from newer entrants.
D) technology assets that require high investment and maintenance are liable to becoming obsolete much quicker than others.
E) the scale of technology investment required to run a business is not a huge enough factor to act as a barrier to entry for new, smaller competitors.
