Hidden Plug In!! Let's just make up a few facts.
If 2/5 were Feature and the rest were Smart, let's just say they made 2 Feature and 3 Smart.
If Smart takes 8/5 as long to produce as Feature, let's just say it takes 8 hours to produce a Smart and 5 hours to produce a Feature.
So it took 3*8 = 24 hours to produce the 3 Smarts and it took 2*5 = 10 hours to produce the Features.
Smart/Total = 24/34, which reduces to 12/17.
Answer choice C.
