Multiple Choice

Antonym of 'transparent'.

Understanding how visibility and light transmission work helps here. Transparent means light passes through so you can see through it. The opposite term is opaque, which means it does not let light through and you cannot see through it. A glass window is transparent, while a wooden door is opaque. Clear is related as a synonym in its everyday sense, not the opposite; lustrous describes shine, not visibility; repeating the same word doesn’t give the opposite. So the best choice is opaque.
