Best Answer Explained in Below-:

The phrase "carry out" is a phrasal verb that means to perform or execute a task, duty, or order. In the context of the sentence "I just had to ____ the orders of my employer," using "carry out" indicates that the speaker is responsible for executing the orders given by their employer. This usage is common in professional environments where tasks or directives need to be followed or completed.

The other options do not convey the intended meaning of executing orders. "Carry on" typically means to continue or persist with an activity, but it does not imply execution of orders. "Carry through" also does not fit properly in this context because it refers more to completing a task despite difficulties rather than simply executing orders. "Carry away" suggests removing something or being overly emotional, which is unrelated to following orders.

Therefore, "carry out" is the most appropriate choice, as it clearly communicates the action of fulfilling or implementing the orders given by one's employer.
