The following pseudocode is executed using the “Scores” dataset. At the end of the execution,variable Count captures the number of students whose total marks are more than the class average (of total marks) but have scored below the subject average in at least one subject. Assume that the variable AvgT holds the value of the average total marks. Similarly, the variables AvgP,AvgC and AvgM hold the value of the average marks of Physics, Chemistry and Mathematics respectively. Choose the correct code fragment to complete the pseudocode.

The following pseudocode is executed using a dataset similar to the "Words" dataset, based on the following paragraph. "Surrounded by nature, Susan often takes a stroll, savoring the soothing sounds of chirping birds.Such moments underline the significance of embracing simple joys in life. Rustlings in the trees suggest squirrels beginning their day, searching for sustenance. Surely, the beauty of a sunrise holds unparalleled magic."
