The correct option is D As you are an industry expert, I was hoping that you could give me some tips
There are a couple of errors in the given sentence.
The first one relates to the modifier, ‘being an industry expert’. The industry expert is the person spoken to (you), and not the speaker (I). This error is corrected by either saying ‘as you are an industry expert’, or ‘being that you are an industry expert’.
The second error is in the use of ‘if’ after ‘hoping’. ‘Hoping’ normally followed by a noun clause beginning with ‘that’(either explicitly stated or implied), or it is followed by ‘for’, or ‘to’. The use of ‘if’ is incorrect. This error is corrected by saying, ‘I was hoping that you could give me some tips’, or ‘ I was hoping for some tips’.
The option that corrects both the errors is option (d).
