The higher the pH, the greater the concentration of Hydroxide (OH-) ions. So, the solution with the pH of 9 is your answer.
No. Calcium Hydroxide does not cause rust, however it can cause corrosion due to its high pH.
when water is added to calcium hydroxide it becomes more dilute and the PH gets closer to 7, therefore its PH would become lower.
A pH=11 is a pH of a basic solution; for example a solution of sodium hydroxide in water.
Calcium nitrate has a neutral solution (pH=7).

A 10% solution of calcium nitrate has a pH of about 6.0. Calcium nitrate is the primary source of water soluble calcium in hydroponics. Prolonged use in other growing media can result in a gradual increase in pH because the negatively charged nitrate ions are taken up faster than the positively charged calcium ions.
No, sodium hydroxide (NaOH) does not have a pH of 7. Sodium hydroxide is a strong base and has a pH greater than 7. The pH of a solution of sodium hydroxide depends on its concentration. A 0.1 M solution of NaOH has a pH of 13.
The higher the pH, the greater the concentration of Hydroxide (OH-) ions. So, the solution with the pH of 9 is your answer.

When excess calcium hydroxide is added to limewater, a suspension of calcium hydroxide particles remains, giving it a milky aspect, in which case it has the common name of milk of lime. Milk of lime is an alkaline solution with a pH of 12.3.
NaOH is a base so it will produce a pH above 7.
pH is 8
