In which poetic form does each stanza contain three lines with an interlocking rhyme scheme?

The poetic form characterized by each stanza containing three lines with an interlocking rhyme scheme is known as terza rima. In terza rima, the rhyme scheme follows a pattern of ABA BCB CDC, and so on, where each stanza's middle line is repeated as the first line of the next stanza. This creates a seamless, interconnected effect throughout the poem.

The other options do not embody this specific structure. Quatrains consist of four lines and can have various rhyme schemes, but they do not share the three-line format with interlocking rhymes. Strophic refers to a song structure with repeated stanzas but isn't limited to specific line numbers or rhyme schemes. Haiku is a traditional Japanese form composed of three lines with a 5-7-5 syllable pattern, but it does not utilize a specific rhyme scheme at all. Thus, terza rima is the clear choice based on its distinct characteristics.
