Answer 1

The Correct Option is D

Step 1:
Statistics deal with aggregates of facts and not single observations. Thus: \[ A = \text{Correct} \]

Step 2:

• Statistics can be misused $\Rightarrow$ B is incorrect
• Statistical laws are not exact like physical sciences $\Rightarrow$ D is incorrect

Step 3:

• Statistics are collected for a pre-determined purpose $\Rightarrow$ Correct
• All statistics are numerical facts, but every numerical fact is not statistics $\Rightarrow$ Correct Thus: \[ C = \text{Correct}, \quad E = \text{Correct} \]

Step 4:
Correct statements are: \[ A,\; C,\; E \] Hence, the correct answer is: \[ \boxed{\text{(4) A, C and E only}} \]
