c. ii., iii., and iv. only

d. i., ii., iii., and iv.

The correct answer is - B. i, iii, and iv only.

Canada, in order to protect and preserve the coastal forests in British Columbia, implemented some measures, some of which where:

- reducing the traffic near the coast;

By reducing the traffic near the coast, and only allowing certain types of tankers to move there, Canada removed the tankers that may cause ecological disasters.

- limiting the construction of pipe lines in the region;

The construction of pipe lines means that there should be lot of trees cut down in order to set them up. Also, the land above and near them should always be cleared in case there's any troubles with it, so with the limiting of their construction, lot of trees have been saved in the forest.

- limiting the logging;

Limitation in the logging and making the timber industry being more sustainable by planting new tress for every tree that is cut down, the forests have been made sustainable, so everyone profits.

radiative zone

explanation    

radiative zone is the layer of the sun which energy is transferred away from the core by radiation. although, the core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius.
