Frequency increases.

Frequency decreases.

Frequency is unaffected.

Frequency increases or decreases depending on how quickly wavelength increases.

v = (lambda)f, with v being the speed of the wave, lambda being the wavelength, and f being the frequency.  The speed of a wave will be constant provided it is passing through the same material the whole time.  It's safe to assume that is the case here.  If you use proportionalites between lambda and f, you can get the answer.

Or picture in your mind:  you are on the beach watching the waves come in - wavelength is the distance between wave tops -- if the distance between the waves increases the number of waves that can come by in a given time would decrease.
