Match the terms in column A with their respective properties in column B.

Column-A	Column-B
i. Glucose	a. Intermediate substance in breakdown of glucose
ii. Yeast	b. Glucose is converted into pyruvic
iii. Glycolysis	c. Uses nutrients for fermentation process
iv. Pyruvic acid	d. Best organic substrate fro respiration

To match the terms in Column-A with their correct properties in Column-B, we can analyze each term step-by-step:

i. Glucose matches with d. Best organic substrate for respiration.
Glucose is a simple six-carbon sugar ($C_6{H}_{12}{O}_6$) that serves as the primary and most preferred respiratory substrate for cellular respiration to produce energy (ATP) in most organisms.

ii. Yeast matches with c. Uses nutrients for fermentation process.
Yeast is a unicellular fungus that undergoes anaerobic respiration (fermentation), utilizing sugars or nutrients to produce ethanol, carbon dioxide, and energy.

iii. Glycolysis matches with b. Glucose is converted into pyruvic acid (completed phrase: Glucose is converted into pyruvic).
Glycolysis is the first metabolic pathway of cellular respiration, occurring in the cytoplasm, where one molecule of glucose is broken down into two molecules of pyruvic acid (pyruvate).

iv. Pyruvic acid matches with a. Intermediate substance in breakdown of glucose.
Pyruvic acid is a three-carbon compound formed at the end of glycolysis, serving as a key intermediate that connects glycolysis to either aerobic respiration (Krebs cycle) or anaerobic pathways (fermentation).

Matching these pairs together:
i → d
ii → c
iii → b
iv → a

Thus, the correct matching option is i-d, ii-c, iii-b, iv-a.
