Identify the bug in this negation handling code snippet:

negate = False
for word in sentence.split():
  if word == 'not':
    negate = True
  elif word in sentiment_dict:
    if negate:
      sentiment_score += sentiment_dict[word]
    else:
      sentiment_score += sentiment_dict[word]
    negate = False

ALoop does not iterate over words

BNegation flag is never reset

CSentiment dictionary is not defined

DNegation does not flip sentiment polarity

Solution:

Step 1: Review negation effect in code
When negate is True, sentiment is added without flipping polarity, so negation has no effect.
Step 2: Identify correct fix
Negation should flip polarity by adding negative sentiment, e.g., sentiment_score += -sentiment_dict[word].
Final Answer:
Negation does not flip sentiment polarity -> Option D
