What word refers to a widespread and destructive fire?

The term "conflagration" specifically denotes a large and destructive fire that causes significant damage, often encompassing a wide area and consuming various materials in its path. This word derives from Latin roots that convey the sense of burning intensely and extensively.

In contrast, the other options do not relate to the phenomenon of fire at all. "Blueprint" refers to a detailed plan or design, commonly used in architecture and engineering. "Abhor" means to regard with disgust or hatred, describing feelings towards actions or behaviors rather than physical events like fires. "Wry" describes a dry, especially mocking, humor or an expression that indicates such humor, which is also unrelated to the concept of fire. Thus, "conflagration" stands out as the sole word accurately depicting a large-scale and destructive fire.
