Let initial price of Maruti Car be Rs. 100.
As price increases 30%, price of car will become, (100 +30% of 100) = Rs. 130. 
Due to increase in price, sales is down by 20%. It means, it is going make 20% less revenue as expected after increment of price.
So, New revenue = (130 - 20% of 130) = Rs. 104. 
The initial revenue was Rs. 100 which becomes Rs. 104 at the end. It means there is 4% increment in the total revenue.

So , Option (C) + 4% is the right answer ✔️
