TL;DR: full MQMs including class-of-service bonuses. Longer analysis/exploration of how you would find this out in similar situations follows.
SkyMiles earning can be really complicated (depending on specific details of operating, marketing, and ticketing carriers in some cases) but the complications mostly come into play for RDMs/MQDs. MQMs have fewer gotchas (not none, just fewer).
To figure out the details, start with the marketing carrier. In this case, that's KL.
Starting from the
SkyMiles partner airlines page, go through to the
KLM page.
That page has three(!) earning tables (though the second and third appear identical to me). Note that exclusions apply, but as long as the operating carrier is KL, KLM Cityhopper, or a SkyTeam partner
other than Jet Airways you will get MQMs and RDMs.
All earning tables have the same MQM accrual, so you get MQMs based on distance and fare class. That's pretty easy. If you bought full J (probably not) you get 200%; discounted business class (C/D/I/Z) gets 150%.
Since your flights are part of a transatlantic itinerary, it doesn't matter if they're DL-ticketed (006) or KL-ticketed (074); both of those would use the top RDM earning chart (dollar-based) plus actual MQDs so there's no class-of-service bonus...just the size-of-payment and Medallion level bonuses.
