Answer: B, D

Explanation:

When comparison is made using double-equals operator (==), it will check the values of variable and convert them to a common type and returns true if both are equals. So comparing number with string having the same value will return true.

Examples:

examples:

1

console.log(23 == "23"); // true

2

console.log(1 == true); // true

Incorrect:

not ===: This is “strict” or “identical” equality.
