Answer:
Option (a) myCar
Explanation:
Option (a) is Correct
If there are two or more words in variable we can use camel case to declare the variable. In camel case first character of first word is either a lowercase alphabet or underscore (_) and first character of second word is a uppercase alphabet. ex: empNum, myCar
So the Option (a) myCar is correct among the given options
Option (b) is incorrect
Since both the first letter of two words are in lower case which is not according to camel case rules
Option (c) is incorrect
The first letter of first word is in lower case first character of second word is a uppercase alphabet but there is a gap so it is not valid .
Option (d) is incorrect
The first word is in upper case and first character of second word is a uppercase alphabet it is not valid.

Explanation:
Logical True and Logical False
These are kinda strange operations. Logical true always results in True and logical false always results in False no matter the premise. These operations are often referred to as “always true” and “always false”.
Binary Operators
Binary operators require two propositions. We’ll use p and q as our sample propositions.
Negation
The negation operator is commonly represented by a tilde (~) or ¬ symbol. It negates, or switches, something’s truth value.
We can show this relationship in a truth table. A truth table is a way of organizing information to list out all possible scenarios.
AND
The AND operator (symbolically: ∧) also known as logical conjunction requires both p and q to be True for the result to be True. All other cases result in False. This is logically the same as the intersection of two sets in a Venn Diagram.
Implication
Logical implication (symbolically: p → q), also known as “if-then”, results True in all cases except the case T → F. Since this can be a little tricky to remember, it can be helpful to note that this is logically equivalent to ¬p ∨ q (read: not p or q)*.
Answer:
In computer memory, zero(0) represents the absence of an electric signal and 1 represents the presence of an electric signal.
Explanation:
Computer memory is used to store data in the form of electrical signals. Electrical signal is used to represent the presence or absence of signal. The data is stored in binary form.
Hence,
In computer memory, zero(0) represents the absence of an electric signal and 1 represents the presence of an electric signal.
