Answer 1

Hint: New moon is defined as the first primary phase that occurs at the moment when the Sun and the Moon are aligned with the Sun and the Moon on the opposite sides of the Moon. Different phases of the moon are known by the different names accordingly.

Complete step-by-step answer:
By definition, New Moon suggests that it is invisible in nature and the earliest thin waxing crescent Moon can be seen after New Moon depends on several other factors which includes clear, unobstructed horizon, atmospheric clarity or seeing and persistence of the naked eye and eyesight of the observer.
Phase is defined as the angle of the moon to the earth which appears different each day.
Basically, there are eight different phases of the Moon named as –
I.Full Moon
II.New Moon
III.Half Moon
IV.Quarter Moon
V.Waning Moon
VI.Crescent Moon
If the new moon day is day $1$then –
The crescent moon – Day $3$
The half moon – Day $7$
The Gibbous moon (waxing) – Day $10$
The full moon – Day $14$
Hence, from the given multiple choices – the option C is the correct answer.
So, the correct answer is “Option C”.

Note: Always remember that the full cycle of Moon Phases takes on average of Twenty-nine days. Remember different terms of the Moon such as “Waxing” means growing and “waning” means shrinking and “Gibbous” means fat.
