PLEAS HELLPPP IT'S URGENT We’re working on micro:bits and I need to find the meaning to these words:

•LED Matrix
•Battery
•Processor
•Accelerometer
•Micro USB Port
•Compass
•Block Editor
•Iteration
•Selection
•Variable
•Algorithm
•Debug
•Number
•String
•Define iteration
•Indefinite iteration
•If Statement
•Text Based programming
•Block Based programming
•JavaScript
•Function
•Syntax

YOU DON’T HAVE TO DO ALL THE WORDS JUST SOME, I WILL GIVE BRAINLIEST!!!

LED matrix is a grid of lights arranged into rows and columns

A battery is a device consisting of one or more electrochemical cells with external connections for powering electrical devices such as flashlights, mobile phones, and electric cars.

A processor is a machine that processes something.

An accelerometer is a tool that measures proper acceleration.

Universal Serial Bus is an industry standard that establishes specifications for cables and connectors and protocols for connection, communication and power

A compas is an instrument containing a magnetized pointer which shows the direction of magnetic north and bearings from it.

A block editor allows you to add Columns block, which basically adds two columns of paragraph blocks.

Iteration is the repetition of a process in order to generate an outcome.

Selection is the action or fact of carefully choosing someone or something as being the best or most suitable.

Algorithm is a process or set of rules to be followed in calculations or other problem-solving operations, especially by a computer.

debug identifies and remove errors from (computer hardware or software).

an arithmetical value, expressed by a word, symbol, or figure, representing a particular quantity and used in counting and making calculations and for showing order in a series or for identification.

I can do the rest if you want, just wanted to give you a head start :)

answer; i believe the correct answer is (a) all trenches must have access/egress;
