Answer:
D diffusion across a membrane
Explanation:
Based on whether or not energy input is required, there are two types of processes viz: passive and active. Passive processes are those that do not require energy input in form of ATP while active processes require energy input to occur.
An example of passive process is DIFFUSION, which is the movement of molecules from a region of high concentration to a region of low concentration across a membrane. Diffusion is passive i.e does not require energy, because movement occurs down a concentration gradient.
Other processes in the options like cell division, DNA replication and protein synthesis all require energy input to occur.
