Primary fuel of heart is fatty acids which carry important beta-oxidation equipment and serve as fuel for heart functions.
Glucose is the primary source of energy for adipose tissue which on breakdown contribute to ATP synthesis.
Liver utilises fatty acids, glucose and amino acids as primary fuel source. When glucose is present in high quanity, it converted into fatty acids.
Hence, the correct option is a) 1:B; 2:C; 3:A; 4:B; 5:C
