Ruby - Arrays

The following code is intended to check if the array nums contains the number 10, but it raises an error. What is the problem?

nums = [5, 10, 15]
if nums.include(10)
  puts "Found 10"
end

AThe array should be flattened before checking

BThe method should be <code>include?</code> with a question mark

CThe number 10 should be a string "10"

DThe <code>if</code> statement syntax is incorrect

Step-by-Step Solution

Solution:

Step 1: Identify the method name error
The method to check presence is include? with a question mark, not include.
Step 2: Understand why error occurs
Calling include without question mark is undefined, causing an error.
Final Answer:
The method should be include? with a question mark -> Option B
Quick Check:
Use include? to check presence [OK]

Quick Trick: Check method names carefully; include? needs question mark [OK]
