Why does the DGT explicitly recommend choosing a Full-Face helmet over an open-face (Jet) helmet?

A)Open-face helmets fail to protect the chin and jaw, which are injured in 35% of motorcycle crashes.Correct
B)Full-face helmets are significantly lighter and put less strain on the rider's neck muscles.
C)Full-face helmets are made of materials that last twice as long as open-face alternatives.

Statistical data confirms that the chin and jaw are highly vulnerable zones in more than a third of all motorcycle accidents. Open-face helmets provide zero structural coverage for these critical areas.
