Statement two and three is correct.
Statement 1 is incorrect. A relative reference changes when a formula is copied to another cell while Absolute references remain constant. However, it is safe to say that an absolute address can be preceded by a $ sign before both the row and the column values. It is designated by the addition of a dollar sign either before the column reference, the row reference, or both. Statement C is also correct. A mixed reference is a combination of relative and absolute reference and the formula (= A1 + $B$2) is an example of a mixed cell reference.

A networking protocol that is used to send data from one network to another network by encapsulation process.
It is the more secured method as it secures the data with the help of encapsulation process. Rest of the protocols are not helpful in security of data.
Answer: b. 11
Explanation:
//The initial value is 1
//let call the value as x
x = 1
//then the user updated the value to 10
//so now x is 10
x = 10
// and update the workflow to 11
//so now the value of x is 11
x = 11
even if the programmer print x, so the output will be 11
Isopropyl is: CH3 - CH - CH3
|
Heptane is: CH3 - CH2 - CH2 - CH2 - CH2 - CH2 - CH3
Then 2,2 isopropyl heptane is:
CH3 - CH - CH3
|
CH3 - C - CH2 - CH2 - CH2 - CH2 - CH3
|
CH3 - CH - CH3.
There you can count that the longest carbon chain has 8 carbon atoms.
So the right name is of an octane.
I will rearrange the chain to show the 8 carbon chain in a row:
CH3 CH3
| |
CH3 - CH - C - CH2 - CH2 - CH2 - CH2 - CH3
|
CH3 - CH - CH3
Now, you can see that the right name is 3 isopropyl - 2, 3 dimethyl octane
