Answer:
column B and column C and use the insert command
Step-by-step explanation:
Columns in excel are the ones identified with letters that are vertically. If you need to insert an additional column, you have to highlight an entire column and use the insert command which will add it to the left of the one you selected. If you need to insert more than one column, you will have highlight the number of columns you need and press insert and that amount will be added to the left of the first one that was highlighted.
So, if you need to add two new columns between column A and column B, considering that they are added to the left of the highlighted colums, you will have to select columns B and C and use the insert command to do it.
