Which statement correctly summarizes triglyceride storage in adipose tissue and their role in energy supply during fasting?

Triglycerides are instantly converted to glucose in adipose tissue and released as blood glucose, which is the sole mechanism by which stored fat provides energy during fasting.

Triglycerides are stored in aqueous vacuoles inside muscle fibers where they are permanently unavailable for energy use, serving only as insulation.

Triglycerides are stored exclusively in the liver as membrane components and cannot be mobilized for systemic energy, so they do not contribute to fasting energy supply.

Triglycerides are stored in adipocytes as large lipid droplets and are mobilized by lipolysis to provide fatty acids for energy when dietary intake is insufficient.
