A is the wff

because in column B

there is no operator between P,Q

2)

Mark the column B

B is the wff

3)

Mark the column B

there should be paranthesis which can seperate

operations

4)

Mark the column A

in column B... C~D is not a wff

so B is not a wff

7)

Mark the column D

neither of them are wff

in column A there has to be a operator between (P-->Q)(R-->S)

and in column B they should be seperated by paranthesis

8)

Mark the column D

neither of them are wff

~ should not be there between <--> operator

9)
