Explanation:

Step1: Analyze "It is symmetrical"

Check if the left and right sides mirror. The 50 - 59 (2 students) and 90 - 99 (2 students) match. 60 - 69 (5) and 80 - 89 (5) match. The middle (70 - 79) is the peak. So it is symmetrical.

Step2: Analyze "It has 2 clusters"

Clusters are groups of data. Here, the data seems to form one main cluster around 70 - 79 with symmetric sides, not two distinct clusters. So this is incorrect.

Step3: Analyze "It is not evenly distributed"

Even distribution would have similar heights. Here, 70 - 79 has 8, others have 2, 5, 5, 2. But since it's symmetrical, the key is symmetry. However, the option "It is symmetrical" is more accurate as the distribution is symmetric (mirror - image on both sides of the center bar).

Step4: Analyze "It has intervals of 5"

The intervals are 50 - 59 (width 10), 60 - 69 (width 10), etc. So intervals are 10, not 5. So this is incorrect.

Answer:

It is symmetrical.
