Consider statement 1:
In 1991, product R fetched the highest revenue.
$\therefore$ Statement (a) is false.
Consider statement 2:
Sum of revenue of P, Q and S in 1994 = 675+160+264
= Rs. 1099 whereas the revenue of R in 1994 is Rs. 1716.
$\therefore$ Statement (b) is false.
Revenue of P and Q together in 1993 = 342+240
= Rs. 582, whereas the revenue of S in 1993 is Rs. 417
$\therefore$ Statement (c) is true.
