Best Answer Explained in Below-:

In the given sentence, the phrase "the first thing that catches your 'eye'" suggests that something unusual or unexpected is being pointed out. Each of the options (A, B, C, and D) represents different components of the sentence that could potentially draw attention.

When we analyze the options, "eye" (A) pertains to perception and doesn't carry visual significance beyond its general meaning. "Building" (B) describes a structure—which may be visually striking, but on its own doesn't imply anything out of the ordinary. "Lights" (D) refers to illumination, which is often used in conjunction with visual effects, particularly in modern architecture.

However, "flour" (C) stands out because it is not an expected element in the context of a building. Typically, flour is a kitchen ingredient, and its presence within a building context is inherently surprising and quizzical. This peculiarity makes it the most noteworthy detail, prompting the phrase "catches your eye." Thus, the unexpected element of "flour" makes it the correct choice, as it is the aspect that creates intrigue and captures attention most vividly in this scenario.
