Solution
The correct option is D boron
Boron is classified as a metalloid while the rest are
considered post-transition metals. Most of the elements in the boron group show
increasing reactivity as the elements get heavier in atomic mass and higher in
atomic number. Boron, the first element in the group, is generally unreactive
with many elements except at high temperatures. Hence, under normal
circumstances boron does not react with water.
