2 answers:
Answer: Option (B) is the correct answer.
Explanation:
A compound is defined as a substance in which two or more different elements in a fixed ratio by mass combine chemically with each other.
For example, chemical formula of water is and it is a compound because here two atoms of hydrogen chemically combine with one atom of oxygen.
And, the ratio of these atoms is 2 : 1. A compound can be broken down into simpler substance by chemical means only.
Whereas an element is a substance that contains only same type of atoms that cannot be broken down into simpler substances.
Thus, we can conclude that water is a compound because it always has two hydrogen atoms for each oxygen atom.

To solve this problem it is necessary to consider two concepts. The first of these is the flow rate that can be defined as the volumetric quantity that a channel travels in a given time. The flow rate can also be calculated from the Area and speed, that is,
Q = V*A
Where,
A= Cross-sectional Area
V = Velocity
The second concept related to the calculation of this problem is continuity, which is defined as the proportion that exists between the input channel and the output channel. It is understood as well as the geometric section of entry and exit, defined as,
Our values are given as,
Re-arrange the equation to find the first ratio of rates we have:
The second ratio of rates is
