Question

Using an improperly sized

screwdriver or not maintaining
proper blade tip thickness will result
in:
A. Reducing the effort required to install or extract a
screw.
B. Neither A or B
C. Marring or distorting the screw heads and making
them difficult to install or extract.

Answer 1

Its c.

Step-by-step explanation:

It will take more work to screw in or remove a screw if you use a screwdriver that is too small for the screw because it won't fit the screw's hole. Similarly, if you use a screwdriver that is too large, it won't fit the screw's hole. If you use a properly sized screw, it will take less work to screw in or out a screw.
