Both earth and moon are subject to the gravitational force to the sun. As observed from the sun, the orbit of the moon
will be elliptical.
will not be strictly elliptical because the total gravitational force on it is not central.
is not elliptical but will necessarily be closed curve.
deviates considerably from being elliptical due to influence of plants other than earth.
The correct option is B will not be strictly elliptical because the total gravitational force on it is not central.
If the moon were to
experience only the gravitation of the earth only then the path would have been
elliptical but in the present case moon experience the gravitational force of
sun as well which distorts the path.
