Why each option

One rack unit (1U) is equivalent to 1.75 inches (44.45 mm), so a 4U server requires 4 times that height.

A4in (10.2cm)

4 inches (10.2cm) is less than 4U, as 1U is 1.75 inches.

B5in (12.7cm)

5 inches (12.7cm) does not correspond to a standard 4U measurement.

C7in (17.8cm)Correct

A rack unit (U) is a standard measure of vertical space in a 19-inch rack, with 1U equaling 1.75 inches (44.45 mm). Therefore, a 4U server requires 4 multiplied by 1.75 inches, which equals 7 inches (17.78 cm).

DSin (20.3cm)

8 inches (20.3cm) is more than the required height for a 4U server.
