The normal quantile plot shows that points are not in staright lines. Points make a curvilinear pattern. And box plot also shows that distribution is not symmetric and there is also an outlier to the distribution.
So on the basis of these graph we cannot conclude that data is normally distributed. And since sample size is small and population is not normally distributed so t-distribution cannot be used.
Option B is correct in both questions.
