In the word "dream," the concept of a phoneme refers to the smallest unit of sound that can distinguish one word from another in a given language. The correct choice is "ea," as it represents the vowel sound /iː/ in "dream." This phoneme is an essential component for distinguishing this word from others, such as "drum" or "drem," where different vowel sounds would change the meaning significantly.

The other parts mentioned, such as "dr," "eam," and "re," represent either combinations of consonants or groups of letters that may not individually convey sound distinctions necessary for phonemic understanding. For instance, "dr" is a consonant cluster that begins the word, while "eam" and "re" do not function independently as phonemes in this context. Thus, understanding that "ea" corresponds to a single vowel sound highlights its significance as a phoneme within the structure of the word "dream."
