This translation says,
If a bhikkhu sees, hears or suspects that it has been killed for him, he may not eat it.
This commentary says,
Furthermore, even cooked fish or meat of an allowable kind is unallowable if the bhikkhu sees, hears, or suspects that the animal was killed specifically for the purpose of feeding bhikkhus.
Both of these imply only the first of your two possibilities.

He is saying that you can only eat meat if someone happens to just put it in your alms bowl randomly from their own food and you have no reason to suspect that the animal was killed specifically for you or monks in general. Remember that these rules were for mendicant monks. They should not be used to justify modern day lay person behaviours. He did not want the monks to encourage or condone the killing of sentient beings but he also did not want to jeopardise the opportunities for giving the teachings by alienating donors by rejecting their food outright.
To bring it up to date and current - if you buy meat or fish in a shop as a customer you can be sure that those animals were killed in order to be sold to customers, therefore you should not buy and eat the meat as this encourages more killing of animals. Nobody cares about alienating butchers and fishmongers by refusing to buy their wares - if anything, say enough people refused to buy their wares then that would be a good teaching for them and they might find a more "right livelihood" and improve their karma.

I would say hear = hear the sound of the animal being killed/ screaming (not for fish or course)
This is based on the interpretation of Dhammavvuddho Thero, he has written a book that contains this subject and also he has given many Dhamma Talks about meat eating. You can google it maybe you will find more details.
He says you should not eat if you see the animal being killed, hear it or suspect it was killed intentionally killed for you, of course you cannot kill or ask someone to do it as well.
There's also another detail: Not all types of meats are allowed, some animals and human flesh should not be consumed for many reasons.
More details here (from Theravada monk Dhammavvuddho Thero):
