The correct answer is: B. character.
Integrity is a quality that is often associated with character. It is the quality of being honest and having strong moral principles. A person with integrity is someone who can be trusted to do the right thing, even when it is difficult. They are also someone who is consistent in their beliefs and actions.
The other options are not as closely related to integrity. Power is the ability to control or influence others. Wealth is the state of having a lot of money or possessions. Influence is the ability to affect the actions or opinions of others.
While these qualities can be admirable, they are not necessarily indicative of integrity. A person with power, wealth, or influence could still act dishonestly or unethically. On the other hand, a person with integrity could still be poor or have little power.
In conclusion, the correct answer to the question “He is considered by every one as a man of integrity” is B. character.
