Answer: (A) ppGpp (Guanosine tetraphosphate)
Under stress conditions, such as nutrient limitation, bacteria accumulate ppGpp, not pppGpp. ppGpp is a signaling molecule that helps regulate the bacterial stress response. pppGpp is less common and not typically associated with stress responses in bacteria.
