This question may invite speculative answers, as the question is not fully defined. The validity of some answers may be based upon opinion.

Puzzles should have a unique solution that clearly fits better than all of the rest, and that does not depend on subjective interpretation. In this question, there are many answers that all seem to be equally valid, and all of the answers (including the 'official' one!) ignore some information in the puzzle: namely, the letters and emoji. This is exactly the type of question that the "too broad" and "speculative" answers are for.
