``python 1 data = {'a': 1, 'b': 2, 'c': 3} 2 print(data['a'], 'b']) ``

Question

1 data = {'a': 1, 'b': 2, 'c': 3}
2 print(data['a'], 'b'])

Options

• A(1, 2)
• BThe code is erroneous.
• C('a':1, 'b':2)
• D[1,2]

• A
  11% (4)
• B
  72% (26)
• C
  14% (5)
• D
  3% (1)

Explanation

Option B is correct because line 2 contains a SyntaxError: the closing square bracket ] in print(data['a'], 'b']) has no matching opening [, making the code impossible to parse - Python never even runs it.

Why the distractors fail:

• A (1, 2) - plausible if you assume data['a'] and data['b'] were both accessed correctly, but the broken syntax prevents any output.
• C ('a':1, 'b':2) - Python never prints dict entries in that colon-separated format, and the code doesn't even attempt to print keys.
• D [1, 2] - nothing in the code constructs or prints a list; the stray ] is a delimiter mismatch, not the start of a list literal.

Memory tip: Train your eye to scan for bracket balance - every [, (, and { needs a matching closer in the right order. A lone ] or ) with no opener is an instant SyntaxError, so the answer is always "erroneous" before you even think about the output.
