Which of the following is the correct syntax to declare a tuple with an Int and a String in Swift?

Alet person: (Int, String) = (25, "Alice")

Blet person = Int, String = (25, "Alice")

Clet person = Int: 25, String: "Alice"

Dlet person: Int, String = (25, "Alice")

Step-by-Step Solution

Step 1: Check tuple declaration syntax
Correct tuple syntax uses parentheses with types inside, then assigns values in parentheses.
Step 2: Validate each option
let person: (Int, String) = (25, "Alice") correctly declares a tuple type and assigns matching values. Others have syntax errors or wrong format.
Final Answer:
let person: (Int, String) = (25, "Alice") -> Option A
Quick Check:
Tuple syntax = (Type1, Type2) = (value1, value2) [OK]

Quick Trick: Use parentheses for tuple types and values [OK]
