Ruby - String Operations

The following Ruby code is intended to split a string into words and then join them with a space, but it raises an error. What is the problem?

text = "hello world"
words = text.split
joined = words.join
puts joined()

AThe variable <code>words</code> is not an array.

BThe method <code>split</code> requires an argument.

CThe call <code>joined()</code> is incorrect syntax.

DThe <code>join</code> method cannot be called without a separator.

Step-by-Step Solution

Solution:

Step 1: Check the method calls
split without arguments splits on whitespace correctly. join can be called without arguments to join with empty string.
Step 2: Identify the error in puts joined()
In Ruby, calling a variable like a method with parentheses joined() causes an error because joined is a string, not a method.
Final Answer:
The call joined() is incorrect syntax. -> Option C
Quick Check:
Calling string like method with () = error [OK]

Quick Trick: Don't add () when printing variables in Ruby [OK]
