Option 1 states that coconut is cultivated in areas 1, 2, and 3. By looking at the map, it is clear that option 1 is correct. Areas 1 and 2 have shading representing coconut cultivation, and area 3 also has a small shaded portion, indicating that coconut may be cultivated in that area as well.

Option 2 suggests that coconut is cultivated in areas 1, 2, and 4. However, there is no shading or indication of coconut cultivation in area 4, so option 2 is incorrect.

Option 3 states that coconut is cultivated in areas 3 and 4. While area 3 does have a small shaded portion, area 4 does not have any indication of coconut cultivation. Therefore, option 3 is incorrect.

Option 4 suggests that coconut is cultivated in all four areas. However, as mentioned earlier, there is no indication of coconut cultivation in area 4. Therefore, option 4 is also incorrect.

So, the correct answer is option 1, which states that coconut is cultivated in areas 1, 2, and 3.
