Solution

The correct option is B X - Gallium (Ga); Y - Metal; Z - Lustrous
X- Gallium (Ga): Of all the metals, gallium (29.76 °C) and caesium (28.44 °C) have very low melting points that they can melt even at room temperature.
Y- Metal: Alkali metals (sodium, potassium, lithium) are so soft that they can be cut with a knife.
Z- Lustrous: Iodine is a non-metal but is lustrous in nature.
