The answer is D. If wavelength changes , then frequency and time period will also change. Wavelength is inversely propotional to frequency and directly propotional to time period.

Antarik Maity from Bharatiya Vidyabhaban, Kolkata

The correct answer should be D. Because temperature of air increases, density decreases and so, frequency of sound increases. But, according to me, it may or may not affect the wavelength, but the time period will definitely decrease. The options are a bit confusing.....

no it can not be option d as temperature has no effect on frequency. Wheather temperature increases or decreases frequency remains unchanged. So, the answer could be either time period or frequency.
