Answer:
A. a person who performs charitable acts for the betterment of humanity.
Step-by-step explanation:
I believe the underlined word is "philanthropists."
A "philanthropist" is a person who usually donates money for the common good or the society's welfare. Donation may also be in the form of skills or the person's time and talent.
For example, Bill Gates, the 2nd richest man in the world, donated a huge amount of money in order to support the research of finding a vaccine for corona virus. Another example is Warren Buffet, the 4th richest man in the world, who donated much of the Berkshire Hathaway stocks to charity. So this makes choice A correct.
