What is not a 21st-century skill that can a person thrive today?
a. applying knowledge to real-world scenarios.
b. education beyond high school, with a minimum of college or technical training.
c. ability to use critical thinking, problem solving, and communication skills, and collaborate with others.
d. ability to memorize and regurgitate information on tests.

Ability to memorize and regurgitate information on tests is the skill that can’t help a person to thrive today in this modern 21st century.

Option D

Explanation:

Thriving in this modern 21st century is not as easy as it used to be in the early 20th and 19th centuries.  So there is a need to develop skills like implementing one's knowledge to real-world structures which will sure help a person to understand and explore more.

Statement B also will sure be helpful to survive in modern society and a person can also improve his/her critical thinking, problem solving and other skills to thrive through this century.

But even though memorizing and regurgitating information can help you get good grade it will never be that helpful in other ways, So option D can be concluded as the right answer.
