Select the correct combination of mathematical signs to sequentially replace the blanks from left to right to balance the given equation.
$6\text{ \_ }2\text{ \_ }0\text{ \_ }8=20$

Let's test the options sequentially by replacing the blanks with the mathematical signs and applying the BODMAS rule:
*Option A ($\times ,+,+$):**

$$6\times 2+0+8=12+0+8=20$$

Since $20=20$, this combination balances the equation perfectly.
*Option B ($-,\times ,+$):**

$$6-2\times 0+8=6-0+8=14\ne 20$$

*Option C ($+,\times ,+$):**

$$6+2\times 0+8=6+0+8=14\ne 20$$

*Option D ($+,+,\times$):**

$$6+2+0\times 8=6+2+0=8\ne 20$$

Therefore, option A is the correct combination.
