Triggers are often used to enforce business rules, maintain data integrity, or perform additional actions based on the occurrence of these events.To create a trigger in SQL, the "CREATE TRIGGER" statement is used. This statement allows you to define the trigger's name, the event that triggers it, the table it is associated with, and the actions to be performed when the trigger is fired. The trigger can be written in SQL or in a specific programming language supported by the database system.Therefore, the correct answer is: c. The SQL CREATE TRIGGER statement.

Answer:

triangular ##&((+ hhvbh. hhhb hhv

Answer:

for i in range(1, 6):

   print(("# " * i).rstrip())

Explanation:

You need to print one hashtag, then 2, then 3, and so on. We can use Python's string multiplication to get each line quicker.

String multiplication is an easy way to repeat the same string a certain number of times. It's done by multiplying the string to a number.

For example,

"hello" * 6

>> "hellohellohellohellohellohello"

If we multiply the string "#" by any number, we would get a number of hashtags side by side, without any space. To easily avoid this, we can multiply "# " instead to automatically put a space to the right of each hashtag.

We can use a for loop that goes through range(1, 6) to print out 5 rows.

for i in range(1, 6):

Then, we can print the string "# " multiplied by i.

print("# " * i)

However, this will also put a space at the end of the string, which we do not want to print. Hence, we can use the .rstrip() method to strip the string of any spaces on the right. We will first put the whole string in parentheses, then invoke rstrip on it.

print(("# " * i).rstrip())

Let's put both lines together.

for i in range(1, 6):

   print(("# " * i).rstrip())
