Q1: This card is linked to a Digimon. If this card activates a link effect, is that effect considered a Digimon effect or an Option card effect?
It's considered a Digimon effect.
Q2: Due to an effect, I can't use an Option card. Can I pay this card's link cost and link to one of my Digimon?
Yes, you can link it. Linking a card isn't the same as using an Option card, therefore a card can still get linked when you can't use Option cards.
Q3: Can I also use this card's Main effect to link to a Digimon in the breeding area?
Yes, you can also link to a Digimon in the breeding area.
Q4: Can I use a "you may link this card to 1 of your Digimon on the field without paying the cost" effect to link to a Digimon even if it doesn't have DP and is in the breeding area?
Yes, you can. However, a Digimon without DP won't be considered to have DP from link DP.
