B)Charles Dickens is the answer.
In 'The Portrait of a Lady' by Khushwant Singh, the narrator depicts his grandmother as someone that displays immeasurable love and selflessness.
She spends her life by taking care of the narrator during his youth and even though he grows and keeps his distance, she remains loving and letting him pursue his interests.
The narrator has a great feeling of respect for his grandmother and though she is not physically beautiful, he describes her inner beauty by comparing her to the purity of nature. The narrator also remarks that she was a lady to the last.
Technology, easy communication methods that’s kinda all I can think about
She has some regrets about not spending more time with her grandfather.
I believe this is the answer because she talks about how their was a slight language barrier and she was preoccupied with life but now that he is gone she wishes she could know more about him.
