Solution

The correct option is B The edge of the needle is pointed
Because the specific gravity of the needle is greater than that of water displaced by it.
Specific gravity (or relative density) is given by:
$\frac{D e n s i t y o f S u b s t a n c e}{D e n s i t y o f W a t e r a t 4^{o} C}$

The average density of iron needle is greater than water, therefore, it sinks.
