Explanation:

- The question asks for the ratio of the actual production of ACs in March and April to the target production of ACs in January and April combined.

- To solve this, actual production numbers for March and April would be summed up.

- Similarly, target numbers for January and April would be added up.

- The two sums would then be compared to find the correct ratio.

- Option 1 suggests a 6:5 ratio.

- Option 2 presents a 5:6 ratio.

- Option 3 claims a 5:2 ratio.

- Option 4 offers a 2:5 ratio.

Without specific production and target numbers, the solution depends on comparing actual patterns to target goals. Given your choice: Option: 1 - 6:5 is correct.
