Doubt regarding Exemption and grace for r16

Bro my friend belongs to r16 regulation he has m1 (17i+18e= 35 marks) and ldica as backlogs, can he apply grace for m1 and ldica as exemption.

Or can he leave two subjects for exemption both m1 and ldica? @Rahul
What's the no.of credits assigned for M1 & LDICA ?
M1 and ldica both 3 credits, the doubt is... which one is professional elective and optional elective, or they matter or doesn't matter for exemption
