Which one of the following is not a blood type for humans?

Uh, there's no such thing a Type D.

Dunno what my blood type is but it’s definitely red in colour…I nearly to took my ear off shaving… I lost concentration!!!!! Lol sometimes you guys take things far to seriously not everyone can be right 100% of the time and we all read things wrongly at times the trick is to remember this and once you gain answers to any of the questions you have or have been asked by friends or teachers or in fact by anyone try to learn a little more then pass it on but do it pleasantly and with patience every one in the human race can learn and teach us from their experiences and knowledge the trick is to listen and not to be ignorant and always try. Sorry I’m having a Yoda day! Lol

plus, the picture shows the three blood types. just saying

horses have 15? some large number.

Calmin, there is no D ,that's why they asked the question ⁉️

I’ve never heard of a person Having a blood type “ D” so I guessed that one

I took it from the question that although humans don't have blood type D, some creatures do? Is that right?

Ben Dover (mobydog1973), what does that mean

What if there would be a blood type D!

bruh its D because the picture has no D so D
