Answer:

C. Increasing wavelength.

Explanation:

Wavelength is given by

[tex]\lambda=\dfrac{v}{f}[/tex]

where,

v = Speed of sound in the medium (constant)

f = Frequency

It can be seen that wavelength is inversely proportional to frequency

[tex]\lambda\propto \dfrac{1}{f}[/tex]

Here, the frequency is decreasing so the wavelength will increase.

Hence, the answer is  C. Increasing wavelength.
