It has been observed that online education(a)/system has drawbacks(b)/in addition to challenge(c)/No Error(d)

The correct answer is - "in addition to challenge"

Key Points

• The error lies in 4th part of the sentence.
• There is an error in the word "challenge" should be replaced by "challenges".
• Here the word "challenge" that is singular is inconsistent with number of its previous words that is drawbacks.
• If we read like - "several drawbacks in addition to challenges" it is well connected with the context.

 Correct Sentence: It has been observed that online education system has several drawbacks in addition to challenges.   

Additional Information

• " Singular + in addition to + singular " is correct form.
• "Plural + in addition to + plural " is correct form.
