Answer:
d. You might have entered a letter for the col_index_num instead of a number.
Step-by-step explanation:
The answer is the option d.
In the col_index_num, we have to provide of the column number we want to refer to. In case some letter is typed by mistake, it will give an error.
An argument col_index_num of 1 returns the value in the first column; a col_index_num of 2 returns the value in the second column in table_array, and so on.
Excel returns an error value if the argument is a text, as well as if it is less than 1 or greater than the number of columns.
