The Correct Option is D

Solution and Explanation

Two separate errors sit in the underlined phrase. After the verb "help", the bare infinitive is required, so "help improving" is wrong and should read "help improve". Also, the word right before "health" must be the adjective "digestive", not the noun "digestion", since it describes the noun "health".

  1. Option A: repeats both errors, the gerund "improving" after "help" and the noun "digestion" used as an adjective.
  2. Option B: "can help improved" pairs "help" with the past participle "improved", which is not valid after "help", and it still leaves "digestion" uncorrected.
  3. Option C: "could be helping to improve" fixes the adjective but turns the sentence needlessly wordy, replacing a simple modal with a continuous form the sentence does not need.
  4. Option D: keeps the original modal "could", uses the correct bare infinitive "help improve", and switches to the adjective "digestive", fixing both errors cleanly.

The correct replacement keeps "could help improve" with the bare infinitive and switches to the adjective "digestive", which is the given option (e), so the folded answer here is option 4.
