Which of the following is the correct syntax to zip two arrays a and b in Ruby?
Aa.zip(b)
Bzip(a, b)
Ca.zip = b
Dzip a, b
Step-by-Step Solution
Solution:

  1. Step 1: Recall Ruby method call syntax

    In Ruby, methods are called on objects with dot notation, so a.zip(b) is correct.

  2. Step 2: Identify incorrect syntax

    The other options do not follow Ruby's method call syntax and will cause errors.

  3. Final Answer:

    a.zip(b) -> Option A

  4. Quick Check:

    Method call with dot and parentheses = A [OK]
Quick Trick: Use dot notation: array.zip(other_array) [OK]
Common Mistakes:
  • Using zip as a standalone function
  • Assigning zip like a variable
  • Omitting parentheses incorrectly
