Answer :
Answer: b. unrelated
Explanation:
There are several types of diversification strategies that a company can follow in order to better take advantages of the opportunities offered by integrating business interests in various industries.
Some companies are not like this however as they follow an unrelated diversification policy where they do not integrate the different divisions that make up the company or make any effort to transfer core competencies. Instead they generally add divisions that do not relate with the previous divisions that they have and leave them to run on their own.
This is what Hutchison Whampoa is doing so this is an unrelated diversification strategy.
