Let us calculate the surface area of the rectangular prism given its dimensions: length $l = 2$, width $w = 8$, and height $h = 6$.

Formula for Surface Area of a Rectangular Prism:

$\text{Surface Area} = 2(lw + lh + wh)$

Step-by-Step Calculation:

1. Calculate $lw$: $lw = 2 \times 8 = 16$

2. Calculate $lh$: $lh = 2 \times 6 = 12$

3. Calculate $wh$: $wh = 8 \times 6 = 48$

4. Add these values and multiply by 2: $\text{Surface Area} = 2(16 + 12 + 48) = 2 \times 76 = 152$

Final Answer:

The surface area of the rectangular prism is: $\boxed{152 \, \text{units}^2}$

This corresponds to the GRAY option.
