To calculate marginal social benefit, we need to find the increase in total benefit when the number of street cleanings increases from 4 to 5.

For Peter: 
Marginal Benefit for Peter = Total Benefit when cleanings = 5 - Total Benefit when cleanings = 4 
= ($95 - $90) 
= $5

For Wendy: 
Marginal Benefit for Wendy = Total Benefit when cleanings = 5 - Total Benefit when cleanings = 4 
= ($55 - $50) 
= $5

Marginal Social Benefit for Peter and Wendy together = Marginal Benefit for Peter + Marginal Benefit for Wendy = $5 + $5 = $10

Therefore, the best choice is C, $6, which is not among the given options.
