VPESR is an acronym (a word composed of the first letters of a phrase) that stands for Valence Shell Electron Pair Repulsion.
It's a scientific theory in the field of chemisty, and it predicts the shape of a molecule based on what atoms form this molecule.
If you want to understand the meaning of the name, you can devide it into
Valence shell electron
-electrons that are on the "outside" of the atom and can form bonds with other atoms
and it's the repulsion of these electrons that is being predicted.

The correct answer is Letter A, Archie.
Answer:
myInt=40
myFloat=4.8
Explanation:
First look at the function definition .It has two arguments intVal is passed by reference while floatVal is passed by value.So the changes done on the myInt variable will be reflected on the original argument because when a variable is passed by reference the the changes are reflected on the original argument but when a variable is passed by value the function created a duplicate copy of it and work on them so changes are not reflected on the original argument.So myInt will get doubled while myFloat will remain the same.
