I dont think it can be solved as time is not mentioned
Answer: Option <em>a.</em>
Explanation:
Kepler's 2nd law of planetary motion states:
<em>A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time.</em>
It tells us that it doesn't matter how far Earth is from the Sun, at equal times, the area swept out by Earth's orbit it's always the same independently from the position in the orbit.
The human eye is one of the most valuable sense organ. The closest object that a typical young person with normal vision can focus closest to is 25 cm
The lens in the eye forms the image on the retina. The image formed is real and inverted. The retina is a very delicate membrane containing numerous light sensitive cells.
This light sensitive cells gets activated when light falls on it and generates electric signals. These electric signals are sent to the brain via the optic nerves present in the eye. The brain finally processes these signals and thus we see the object clearly.
The ability of the lens of the eye to adjust its focal length accordingly is called the power of accommodation,
The minimum distance, at which the object can be seen clearly without any strain is called the least distance of distinct vision.
To see an object clearly without any strain is when we place it at about 25 cm from the eye.

Flammable and combustible liquids themselves do not burn. It is the mixture of their vapours and air that burns. Gasoline, with a flashpoint of -40°C (-40°F), is a flammable liquid. Even at temperatures as low as -40°C (-40°F), it gives off enough vapour to form a burnable mixture in air.
Hope this helps
