Answer:
Option B
Transfers energy to the water
Explanation:
Warm air transfers energy to the water when it flows over cold currents. This means that the warm air loses heat energy to the cold currents thus, raising its temperature.
Whenever there is a temperature difference between two bodies in contact with each other, the Fouriers law explains that there is always a transfer of heat from the hotter body to the colder body until they become the same temperature.
Thus, following this, heat will flow from the warm air to the cold currents.

See explanation
Explanation:
Qualitative analysis in chemistry is a method used to determine the ions present in a solution chiefly by means of chemical reactions.
In this case, I suspect the presence of silver ions and/or barium ions. The first step is to add dilute HCl. This will lead to the precipitation of the silver ion as AgCl. If a white precipitate is formed upon addition of HCl then Ag^+ is present in the solution.
Secondly, I add a carbonate such as NH4CO3(aq). This will cause the barium ions to become precipitated as barium carbonate. Hence, the formation of a white precipitate when NH4CO3(aq) is added to the solution indicates the presence of barium ion in the solution.
Actually Welcome to the Concept of the Chemistry.
The reaction that Is opposite of the decomposition is
==> Synthesis Reaction.
==> Catalyst always Speeds up any reaction, so that it quickly reaches to it's Equilibrium point and gets stabilize.
There are two kinds of buffer
a) acidic buffer
b) basic buffer
They both resist change in pH on addition of small amount of strong acid or base
as asked in question we will consider addition strong acid that is [H+]
a) acidic buffer: it is a mixture of weak acid and its salt with strong base
say CH3COOH + CH3COO-Na+
When we add H+, the H+ are being consumed by acetate ions to give acetic acid
CH3COO- + H+ ---> CH3COOH
So it accepts H+
b)basic buffer
Example: NH4OH + NH4Cl
when we add H+ , the OH- will react with it to form water
So it accepts H+
