Step 1: Alyzing Seals (a):
Seals were crucial tools used to facilitate long-distance trade and administrative regulation. When goods were tied and sent from one place to another, a layer of wet clay was applied to the knot, and a seal was stamped on it. If the seal impression remained intact, it proved that the goods had not been tampered with. It also carried the identity of the sender, acting as a direct instrument of authority and administration. Hence, $a \rightarrow ii$.
Step 2: Alyzing Weights (b):
Harappans used a highly regulated, standardized system of weights made from a stone called chert. These weights followed a strict biry system at lower denomitions ($1, 2, 4, 8, 16, 32$, etc., up to $12,800$) and a decimal system at higher values. They were utilized as a standardized unit for measuring commodities, metals, and precious stones. Hence, $b \rightarrow iii$.
Step 3: Alyzing Beads (c):
The production of beads was a major craft industry in Harappan settlements like Chanhudaro and LOTHAl. Beads were crafted out of diverse materials like carnelian, jasper, crystal, steatite, copper, bronze, and gold. They exhibited highly specialized craft technologies and craftsmanship. Hence, $c \rightarrow i$.
Step 4: Alyzing Faience (d):
Faience is a artificially produced material made from ground sand or silica mixed with color and a gum, which was then fired. Miniature pots of faience were rare, luxury items that required complex craft processing and were often used to make premium pottery vessels or cosmetic containers. Hence, $d \rightarrow iv$.
Step 5: Fil Match:
Matching the pairs yields: a-ii, b-iii, c-i, d-iv, which is option (A).
