Correct Answer: Below Basic


Solution : Average performance = $\frac{\text{Sum of performances in all subjects}}{\text{Number of subjects}}$ 
Average performance for Below Basic = $\frac{40+19+41+34+8}{5}$ = 28.4
Average performance for Basic = $\frac{35+45+29+21+5}{5}$ = 27
Average performance for Proficient = $\frac{20+25+25+33+34}{5}$ = 27.4
Average performance for Advance = $\frac{5+11+5+12+52}{5}$ = 17
Hence, the correct answer is Below Basic.
