Answer:
A is definetely the correct answer
You have to be more specific
I'd go with However because it is hot, BUT they can't complain. It's the most logical one
However is just another word for BUT.
Make sure you start with an introduction of yourself, and make sure to state “thank you for the opportunity of working here” then go into “I am sad to say I will be leaving this job” and explain why and it’s that simple(:
I would say b since noun means a person, place, or thing.
