The correct option is A
$C l a s s I l e v e r$

Depending upon the relative positions of the effort, load and fulcrum, levers are classified into 3 types.

(1) $C l a s s I l e v e r$

(2) $C l a s s I I l e v e r$

(3) $C l a s s I I I l e v e r$

In both scissors and pliers, the fulcrum is located in between load and effort. Hence, they belong to class I lever.
