Both of them have high electronegativity. Hence they both tend to gain electrons to gain stability.
This is a tough one but the answer is water
think of it this way the ocean is water
When you use exponents, think of it like this. 1 squared is 1 x 1. 1 cubed is 1 x 1 x 1. And 1 to the power of 4 is 1 x 1 x 1 x 1. And so on. You basically just multiply them by themselves. 0 to the power of any exponent is 1, well that's just a rule. It doesn't make much sense but it's easy to remember and I wouldn't worry about it.
The answer is B. bases measure below seven
