Explanation

Based on a typical schedule diagram for this type of question, Task 1 is the initial task that enables both Task 2 and Task 4 to begin once it finishes (Finish-to-Start relationship). Task 3 depends on the completion of both Task 1 and Task 2, meaning it cannot start until both predecessors are complete. FS (Finish-to-Start) is the most common dependency type, meaning the successor task cannot start until the predecessor has finished. Option A is incomplete because it misses Task 1 as a predecessor to Task 3. Options C and D rearrange or omit key relationships that do not align with the inferred schedule structure.
