Re: Voya Retirement Insurance and Annuity Company and its Variable Annuity Account C
Post-Effective Amendment No. 25 to Registration Statement on Form N-4
Prospectus Title:  Voya MAP Plus NP^SM
File Nos.:  333-109860 and 811-02513

Ladies and Gentlemen:

The undersigned serves as counsel to Voya Retirement Insurance and Annuity Company, a Connecticut life insurance company (the “Company”). It is my understanding that the Company, as depositor, has registered an indefinite amount of securities (the “Securities”) under the Securities Act of 1933 (the “Securities Act”) as provided in Rule 24f-2 under the Investment Company Act of 1940 (the “Investment Company Act”).

In connection with this opinion, I have reviewed the N-4 Registration, as amended to the date hereof, and this Post-Effective Amendment No. 25. I have also examined originals or copies, certified or otherwise identified to my satisfaction, of such documents, trust records and other instruments I have deemed necessary or appropriate for the purpose of rendering this opinion. For purpose of such examination, I have assumed the genuineness of all signatures on original documents and the conformity to the original of all copies.

I am admitted to practice law in Connecticut, and do not purport to be an expert on the laws of any other state. My opinion herein as to any other law is based upon a limited inquiry thereof which I have deemed appropriate under the circumstances.

Sincerely,

/s/ J. Neil McMurdie
