what is the present employer to fill in Ds160 form if the present employer is different from petition


My H1 was filed by one of consultancy in india - at that time i am working for a company A in Bangalore and same company details are provided as present employer. Before few months back i moved to another company B in Hyderabad - at that time lottery is not done.
Now My H1 petition was picked up in lottary and also approved. When i filling DS160 form which company should need to mentioned as present employer. If i fill company A as present employer will there be any problem.

when asked my consultancy they told me to put Company A as present employer … not sure will there be any rejection in this case.
