Which languages are statically typed?
A
C
B
Python
C
Javascript
D
Java
E
Ruby
Explanation: 

Detailed explanation-1: -Some common examples of programming languages that belong to this category are Java, Haskell, C, C++, C#, Scala, Kotlin, Fortran, Go, Pascal, and Swift.

Detailed explanation-2: -A language is dynamically-typed if the type of a variable is checked during run-time. Common examples of dynamically-typed languages includes JavaScript, Objective-C, PHP, Python, Ruby, Lisp, and Tcl.

Detailed explanation-3: -In the JavaScript community, Flow and TypeScript have emerged as the two main options for enabling static type checking: Flow is a static type checker for JavaScript. It is an open-source tool developed by Facebook. TypeScript is a statically typed superset of JavaScript that compiles to plain JavaScript.

Detailed explanation-4: -Dynamically-typed languages are those (like JavaScript) where the interpreter assigns variables a type at runtime based on the variable’s value at the time.

Detailed explanation-5: -A language that is dynamically typed verifies at runtime that the values in an application conform to expected types. By comparison, a statically typed language such as the Java programming language does most of its type checking at compile time, checking the types of variables, not values.
