The formation of thunder clouds, also known as cumulonimbus clouds, involves a series of processes:

Option 1 suggests only condensation and high temperature and humidity. While these are important for thunder cloud formation, they are not the only factors.

Option 2 includes high temperature and humidity, orography, and vertical wind. These play a key role in thunder cloud development, but the absence of condensation, which allows for cooling and formation of the cloud body, makes this option partially correct.

Option 3 suggests condensation, orography, and vertical wind. Although these are essential, the lack of high temperature and humidity means the air would not have sufficient moisture for cloud formation.

Option 4 includes all of the listed phenomena: condensation, high temperature and humidity, orography, and vertical wind. These are all needed - high temperatures and humidity provide moisture, orography (mountains) helps air to rise and cool, condensation permits the formation of cloud droplets, and vertical wind gives rise to the thunderstorm itself. This makes option 4 the correct answer.
