Which is one factor that will affect the type of cloud that will form? -altitude. -wind direction. - color of clouds. - size of pellets

As air rises in the atmosphere, it becomes cool because air pressure is less at that altitude. So, when the air cools to a certain degree, it is unable to hold the water vapor and this vapor becomes water droplets and thus, cloud is formed.

Other factors also influence cloud formation such as topography, humidity, etc but according to the question and with regards to the options available, the correct answer is altitude.

An altitude affects the formation of cloud because the base of the cloud forms at an altitude where the rising air cools and condensation starts.

Cloud formation

Generally, the temperature, wind and other conditions are what decides where a cloud forms and what type of cloud it will be.

Other factors that influences a cloud formation includes:

topography
humidity etc

Hence, an altitude affects the type of cloud to form because the base of the cloud forms at the altitude at which the rising air cools and condensation starts.

Therefore, the Option A is correct.
