கொடுக்கப்பட்ட மாற்றுகள் 1, 2, 3, 4 இல் இருந்து படம் X ஐ நிறைவு செய்யவும்

Each quarter of X has a diamond near its outer corner, and one circle runs round the centre through every quarter. The missing bottom-left quarter must have a diamond near its bottom-left corner and the circle's arc around its top-right corner (the centre of X). Only option 2 shows both.
