<u>Answer</u>: Option b) 2
<u>Explanation</u>:
- Significant figures are the digits which play a role in defining a measurement that is they carry some meaning.
- There are <em>three</em> essential rules to find out the significant figures in a given number:
- <u>Rule 1</u>: Non-zero digits such are always significant.
- <u>Rule 2</u>: The zeroes after a non-zero number in decimal are also significant. An example is if the number is 0.0500 then the zeroes after 5 are considered significant, however, the zeroes before 5 are not significant.
- <u>Rule 3:</u> The zeroes placed between any two significant digits are also considered as significant e.g in 202 the zero is significant.
- Therefore, in the number 0.020 km, there are <em>two</em> significant digits, one is 2 and the other is the last zero placed after 2.

Aged people have a large amount of osteoclasts which is responsible for the the breakdown of bone for repairs and remodification which poses a great risk for decreased and weakened bones.
The 9 yr old grand daughter however has large amounts of osteoblasts which help in bone production and translates to stronger bones.
This features and findings are the assumed and likely reasons why the 75yr old woman had fractures and the 9 yr old grand daughter suffered none.
