An active solar heating system . absorbs and stores energy directly from the sun collects and stores heat by way of heat.absorbing fluids uses mirrors to collect and focus solar energy uses photovoltaic cells to generate electricity requires the sun to heat water to a boiling temperature

## Step 1<br />An active solar heating system is a type of solar heating system that uses mechanical devices to collect, store, and distribute solar energy. This is in contrast to passive solar heating systems, which do not use mechanical devices and rely on the natural flow of heat.<br /><br />## Step 2<br />The options provided in the question are different methods of collecting and storing solar energy. We need to identify the one that best describes an active solar heating system.<br /><br />## Step 3<br />The option "collects and stores heat by way of heat-absorbing fluids" is the most accurate description of an active solar heating system. This is because active solar heating systems typically use a fluid (usually water or a special fluid) to absorb the heat from the sun. This fluid is then pumped through a storage system, such as a tank, where it can be used to heat buildings or water.<br /><br />## Step 4<br />The other options do not accurately describe an active solar heating system. For example, mirrors are used in concentrated solar power plants, not in active solar heating systems. Photovoltaic cells are used in solar panels to generate electricity, not in solar heating systems. Lastly, active solar heating systems do not require the sun to heat water to a boiling temperature.
