Solution

The correct option is A Yes
Free trees will be resolved.

$\frac{d}{D} \geq$ resolution power of eye

$\frac{d}{D} = \frac{1}{10^{3}}$
$R P = (\frac{1}{60}) = \frac{1}{60} \times \frac{π}{60} = \frac{3.14}{10.8} \times 10^{- 3}$

Since $\frac{d}{D} >$ resolution power of eye.

$∴$ Tree appear resolved.
