In programming language design, grammar rules define the structure and syntax that a compiler or interpreter uses to understand and process code. This case study explores how formal grammar guides the construction and validation of programs, emphasizing the importance of syntactic precision in language design.Given the following grammar rules:1. -> start finish2. -> ident | ident, 3. -> := 4. -> if then | if then else 5. -> | ; 6. -> := 7. -> X | Y | Z8. -> * | / | Consider the program:start    X := Y * Z;   Z := X finishTasks:1: What is the start symbol of the grammar?2: Using the provided grammar rules, parse the program to illustrate how it is derived from the start symbol. Show each step of the derivation process.3: Determine if the given program adheres to the grammar rules. Is the program valid according to the provided grammar?
