For the given word PREAMBLE, lets start with P. Now PR is not a possible pair as it does not have any letter between them whereas in english alphabets there is 1 letter between P and R. Similarly PE and PA pairs are also not possible. On checking in a similar manner, we can see that EB and AE are the only pairs which meets the requirements. So the correct option is option 3.
