At what stage in the product lifecycle does the sales growth start to slow down?

everybody goes for option B, maturity stage, but maturity means the product gets mature, so at its best en well known, so why not saturation stage? When the product soaks the market, I would see that as negative, so slowing down sales.

At maturity stage......................

b) Maturity stage

is the answer

OPTION b ....................................

I think the same way as Mr.Kinsbergen herein above.

one it is reached saturation stage, sales growth starts to slow down.

Especially when it is maturity stage, it suppose to be grow better as it is come out from pre-matured stage and reached maturity stage an should be more stable..

It is at Maturity Stage. Since, you have customers and their feedback about the product. The product has to be possibly improved from time to time as well.
