(D) The completed table is as follows:
Explanation:
$1$. Simple Diffusion: Passive process,non-selective,no energy required,moves along the concentration gradient.
$2$. Facilitated Transport: Passive process,highly selective (uses membrane proteins),no energy required,moves along the concentration gradient.
$3$. Active Transport: Uses energy $(ATP)$ to pump molecules against the concentration gradient (uphill),highly selective,and requires carrier proteins.
| Property | Simple Diffusion | Facilitated Transport | Active Transport |
| Highly selective | No | Yes | Yes |
| Uphill transport | No | No | Yes |
| Requires $ATP$ | No | No | Yes |
