Correct Answer: B, DTo ensure the content of the confirmation is the same for all three correspondence types (email, text message, and letter), creating one correspondence rule for each type and configuring each correspondence rule to reference a common element containing the confirmation is the most efficient and reliable approach. Option B, which suggests creating one rule for each type that references a common correspondence rule, and Option D, which suggests referencing a common paragraph rule, both achieve this consistency. This method prevents content discrepancies and simplifies updates, as changes to the confirmation only need to be made in one place.
