To determine the risk factor while riding bicycles with friends, we need to assess the options provided and identify whether they pose any potential risks.

A. Leaving your helmet at home: This is a risk factor as helmets provide protection for your head in case of a fall or accident. Not wearing a helmet increases the risk of head injuries.

B. Letting your family know where you will be: This is not a risk factor but, in fact, a safety measure. Letting your family know where you will be can be beneficial in case of an emergency or if someone needs to reach you.

C. Being in a large group of people: This can be a risk factor if the group is not following safety guidelines or traffic laws. Large groups can make it harder for motorists to see cyclists, and coordination within the group becomes important to avoid accidents.

D. Coming home before dark: This is not a risk factor but a safety measure. Riding after dark can be more dangerous as visibility decreases, making it harder for motorists to see cyclists.

Based on the options provided, the correct answer for the risk factor while riding bicycles with friends would be A. leaving your helmet at home. Wearing a helmet is important for the safety of the rider, as it reduces the risk of head injuries in case of an accident.
