b) True

c) Runtime error

d) Compilation error

Answer 1

Answer: B

Reason: In the following JavaScript code, the "?" is being used which is also known as ternary operator". Here it is used to choose one option as a choice among the given two options. However, it is often used to write shorter and simple code because it can be used in the place of "if else" statements.
