Imp - tds in case of two employers in one year???

Tax (Student) (165 Points)

16 January 2017  

Mr. X had two employers for the previous financial year 15-16 (AY 16-17)

He worked for 4months with first employer...

Then he changed jobs and worked for the remaining 8 months with the second employer..

The SECOND employer issued FORM 16 for the year WITHOUT incorporating the salary of the FIRST employer.. 

Can Mr. X still submit FORM 12B after issuance of FORM 16 by the second employer???

What are the options left??
