Answer:
D
Step-by-step explanation:
With each flip of the coin, the chance of it landing on tails is multiplied by half. Hence the chance of landing a consecutive series of tails decreases the more times you flip the coin, but never reaches 0.
A is incorrect as it is possible to land heads on any flip. 
B is incorrect as there is always a possibility of landing tails on every flip. 
C is incorrect as the chance of getting tails on every flip is small (and gets smaller) and hence cannot be considered to be likely. 
Hence D is the answer.
