Exactly!!

Your answer of D is correct. To join the text in two cells together, you can use the concatenation operator "&". The correct formula would be:

D. =Good "&" Morning

This formula will take the text in the cell labeled "Good" and append it with the text in the cell labeled "Morning", resulting in the two strings being joined together.
