If you _____ any problems, let me know and I _____ and help you straight away

• A. Had / would come
• B. Have / will come
• C. Had had / would come
• D. Have / would go

Answer 1

Answer: (B)

Have / will come

This sentence shows a fact and is making a statement about a real and possible situation. Hence, it is using first conditional that employs forms of verbs in present and future tenses. The structure of first conditional is: "If" Clause (If + present simple + comma) followed by Main Clause (Subject + will/other modal + base verb). So, Option B is the correct answer here as it has verbs of present and future tenses. Options A and C cannot be used as they contain verbs of past tense. Option D cannot be used as it would render the sentence grammatically incorrect.
