(E_Name, Salary_in_Lakhs) is the key

(E_Name, Salary_in_Lakhs) → {E_ID, E_Age, E_mail}

E_Name: Nitesh is repeated

Check only for Nitesh

(Nitesh, 9) → (XE005, 24, nitestSE@123)

(Nitesh, R) → (XE023, 24, nitestCE@123)

Since right hand side is not same

Therefore, R cannot be equal to 9

The correct answer is ​0 to 14.

Important Points

• The pH scale is the scale used to express the acidity or alkalinity of a substance based on the concentration of hydrogen ions in its solution.
  • pH scale was discovered by Soren Sorensen.
  • The range of pH scale 0 to 14.
    • If pH < 7 then solution is acidic.
    • If pH > 7 then solution is basic.
    • If pH = 7 then solution is neutral.

Additional Information

• pH means the potential of Hydrogen.
• The strength of acids and bases depends on the number of H⁺ ions and OH^- ions produced, respectively.
• The human body works within the pH range of 7.0 to 7.8.
• When the pH of rainwater is less than 5.6, it is called acid rain.

Statement: x /= 2,

It is compound assignment statement. It is basically a shorthand notation for incrementing the variable on the left by a value on the right.

So, x /= 2 is same as x = x / 2.

Similarly

X -= 2; is the same as x = x – 2 ;

 x*=2; is the same as x=x*2;

Therefore, in given question all the options are 1, 2, 4 are correct. As there are using the compound assignment operators.

But in option 3 x%=2 is not same as x = x/2 as the operators are different.

X%=2 is same as x = x%2
