How could you insert a new row between rows 20 and 21?

a. right-click row 20's row number, and then click insert.
b. right-click a cell in row 20, and then click insert.
c. right-click row 21's row number, and then click insert.
d. right-click a cell in row 21, and then click insert.

If you want to add a new row in Microsoft Excel, you need to use the Insert Row function. However, if you want your row to be placed between two existing rows, the option you should choose is (C) Right-click row 21's row number, and then click Insert. If you right-click on row 20 instead, the new row would appear between row 19 and 20.

solution:

this situation is called an ip conflict.

data from a server is sent in small bits called packets. in an ip conflict, some packets will end up in one computer while some other packets will end up in another computer.

so…overall none of the computers get the data as the original message or picture being sent by the server cannot be retrieved with only half the packets. so it will show up as an error.

thus the final answer is d.
