Choose the correct answer: Consider the following scenario:Activity Act1 shall be carried out.

The correct answer is Option B. This diagram accurately depicts the scenario where activity Act1 is carried out first, followed by activity Act2, and then Act1 is performed again.

Here's why the other options are incorrect:

Option A: This diagram shows Act1 followed by Act2, but Act1 is not repeated.

Option C: Similar to Option A, this diagram depicts Act1 followed by Act2, without a repetition of Act1.

Option D: This diagram has conditional branches, which is not part of the given scenario where the activities are carried out sequentially.

Following the logic from the prompt: Act1 -> Act2 -> Act1, Option B visually represents this sequence with arrows connecting the activities in the specified order.
