Step 1: Break Down the Problem

We need to analyze each sentence option for grammatical correctness, focusing on proper verb forms and sentence structure.

Step 3: Analysis and Detail

1. Option A: "Please wait I solve."
   • This sentence lacks punctuation and correct verb tense.
2. Option B: "Please wait I am solving."
   • This is correct; it uses the present continuous tense appropriately and has proper sentence structure.
3. Option C: "I solving this."
   • Missing the auxiliary verb "am"; incorrect verb form.
4. Option D: "I am solved this."
   • Incorrect verb form; "solved" implies past tense which does not fit the context.
