A is incorrect. This sticking together of like substances is called cohesion. Depending on how attracted molecules of the same substance are to one another, the substance will be more or less cohesive. Hydrogen bonds cause water to be exceptionally attracted to each other. Therefore, water is very cohesive.

B is correct. The property in which water molecules stick to one another tightly. The property in which water molecules easily evaporate into a gas.

C is incorrect. In cohesion, water molecules are attracted to each other (because of hydrogen bonding), keeping the molecules together at the liquid-air (gas) interface, although there is no more room in the glass.

They are all tetrapoda.

Tetrapods are animals (group of vertebrates) with four limbs including amphibians (frogs), reptiles (caimans), birds (parrots) and mammals (hares, humans). Even though the subgroups within Tetrapods differ a lot, they all have various adaptations of the skeleton and muscles that enable them movement on land, adaptations of cranium (for head stability), tissues that reduce water loss (because of living outside the water)…Except amphibians all other tetrapoda are amniotes (have amnion layer around embryo)
