Question: What is called Chronological Age?

Options:

1. Which starts from the birth till death
2. Which starts from level 1 to level 12
3. Which starts from death till birth
4. All of these

Step-by-Step Analysis:

1. Option 1: Which starts from the birth till death

   • Chronological age is typically defined as the amount of time that has passed from a person's birth to the current date. This is the most common and widely accepted definition of chronological age.

2. Option 2: Which starts from level 1 to level 12

   • This option seems to refer to a system of levels, which is not a standard way to measure chronological age. Chronological age is measured in units of time (years, months, days), not levels.

3. Option 3: Which starts from death till birth

   • This option is not logical because chronological age cannot be measured from death to birth. Age is measured from the point of birth onwards.

4. Option 4: All of these

   • Since options 2 and 3 are not valid definitions of chronological age, this option cannot be correct.

Conclusion: The correct answer is:

1. Which starts from the birth till death
