Question

What is the total number of Bravais lattices in orthorhombic crystal system?

• A. \(3\)
• B. \(2\)
• C. \(1\)
• D. \(4\)

Hint:

Orthorhombic has primitive, base centred, body centred and face centred lattices.

Answer 1

The Correct Option is D

Step 1: Recall the table:
Of the $14$ Bravais lattices, the distribution is cubic 3, tetragonal 2, orthorhombic 4, monoclinic 2, hexagonal 1, rhombohedral 1, triclinic 1.

Step 2: Check:
$3 + 2 + 4 + 2 + 1 + 1 + 1 = 14$, which confirms that the orthorhombic system has 4 lattices.

Final Answer:
The count is $4$, option (D). \[ \boxed{4} \]
