Why is VAR(10) not a data type in the exercise considering that 'N' can be considered as the length of the string except if this is in line with the notion that 'N' is different from 'n' as taught in Statistics? In case that will CHAR(n) be considered a data type?

Hi Yinka! Thanks for reaching out. The answer A is incorrect because the CHAR data type is expecting a number and not a letter. You can see that answer D shows just that. Hope this helps. Best, Tsvetelin
