What cloud is highest?

Question

I wanna know what cloud is the highest out of these three stratus, cirrus, and cumulus.

Answer 1

Cirrus clouds are the highest out of the three (they indicate fair weather).

Answer 2

Cirrus for sure

There are 3 types of clouds that belong to the 'High Cloud' group: cirrus, cirrocumulus and cirrostratus. These 3 types can be found between 5000m and 13000m up.

Cirrus is the most common.

There is another that is really the highest of all but was not listed  in your question. Noctilucent clouds are the highest clouds in the sky, however they are not associated with weather like the rest of the ones mentioned. Scientists believe that these clouds are made of frozen water or ice crystals. They are found way up in the mesosphere.
