The concept "glass ceiling" refers to: question 22 options: a. the barrier that prevents women from reaching the top. b. the fact that women's dreams are easily broken. c. the fact that cleaning the home is all most women do. d. the barrier that keeps women in service work

I believe the answer is: A. .the barrier that prevents women from reaching the top.
Glass ceiling usually taken form in a false perception that undermine female's capability in a certain area. For example, there are a general perception that stated men are generally better at math compared to women.
This often become a glass ceiling for women to advance in the career that require strong basis in math such as physics and engineering.
