Hi ANMOL SETH, Answer is B only.
In Glycolysis 8-ATP molecules is the final outcome of ATP molecules.
If you subtract 8 from 38,
you will get 30 ATP only from Krebs cycle and Pre krebs cycle steps.

Total ATP molecules from per glucose	38
NET ATP molecules gained from Glycolysis	-8
ATP molecules gained from Krebs cycle alone	30

A. Respiratory chain: combustion of food with O2

B.Krebs cycle-10 steps produces 30 ATP molecules
C.Oxidative ecarboxylation-one step of krebs cycle
D.EMP-Embden -Myerhoff- pathway- aslo called as Glycolysis
