Correct option is B
Understanding the Terms:
- Median = 50th percentile = 5th decile = 2nd quartile
- 7th decile = 70th percentile
- 3rd quartile = 75th percentile
- 78th percentile = 78th percentile (as is)
Now, convert all to percentiles to arrange them:

Arrange in increasing order:
50% (Median) < 70% (7th decile) < 75% (3rd quartile) < 78% (78th percentile)
Correct Order:
B, A, C, D
