The correct answer is option a and option d.
The ink does not fall out of the dropper because the atmospheric pressure outside the dropper is more and inside the dropper is less.
As the ink dropper is pressed, a lower pressure is created and it sucks the ink due to the ink dropper. After entering into the dropper, the ink will be present at the lower pressure than the outside atmospheric pressure. Liquids like ink cannot flow from lower pressure to the higher pressure. Thus, the ink remains inside the ink dropper without dropping unless more pressure is applied to it by pressing its rubber.

Well from the question's options there are two option which are correct option a(the atmospheric pressure outside is more) as well as the option d (the pressure inside the dropper is less) both are the correct.
A dropper suck the ink in such a way that there is lower pressure development occur inside the dropper surrounding the ink which is low than the atmospheric pressure from the outside environment. And we know that ink like liquids are not able to go to the high pressure area from the lower one. So ink stay in the dropper.
