Of these statement, mark correct choice.(a) Statement 1 and 2 are true and statement 2 is a correct explanation for statement 1.(b) Statement 1 and 2 are true but statement 2 is not a correct explanation for statement 1.(c) Statement 1 is true, statement 2 is false.(d) Statement 1 is false, statement 2 is true.(e)

98. Statement 1 : Statements (i) ~ (P q) (ii) ~ p q and (iii) p ~ q are logically equivalent.Statement 2 : Two statements p and q are said to be logically equivalent iff they have identical

truth values.
