Right option is (b) False

Easiest explanation: It is dependent upon the programmer to choose the variable name while establishing a connection between a global and a persistent variable. Essentially, one may choose to keep the variable name same to avoid confusion in case of multiple sub-functions. But it is not necessary if there are a small number of sub-functions.
