Old company name or new company name in DS 160 after acquisition

[yubeie]

I am a full time employee and planning to attend by h1b visa renewal interview. My Company A got acquired by Company B. The curent I-797 indicates the petitioner as Company A.

I am not sure if I am supposed use Company A (or) Company B in my DS-forms. Can some one please shed some light if you ran into similar confusion?

Per my understanding, If I mention Company B in the DS-Forms, since it does not match the I-797, wouldn't that trigger 221g delays automatically given that VOs do not spend a lot of time with the candidate during the interview?

Thanks!
