Shalini was not bothered by the criticism, which means she was not upset or annoyed by it. She also paid no attention to it, which means she did not listen to it or take it seriously.
The other options are not as accurate. B. troubled, mind is not as accurate because troubled means to be worried or upset, and Shalini did not seem to be worried or upset by the criticism. C. threatened, warning is not as accurate because threatened means to be in danger, and Shalini did not seem to be in danger from the criticism. D. deterred, heed is not as accurate because deterred means to be discouraged from doing something, and Shalini did not seem to be discouraged from doing anything by the criticism. E. shaken, indication is not as accurate because shaken means to be made to feel nervous or upset, and Shalini did not seem to be nervous or upset by the criticism.
