Q.Internal (domestic) trade is itself further divided into two stages, based on the scale of the transaction and the identity of the buyer. These two stages are:
(A) Export trade and Import trade
(B) Wholesale trade and Retail trade
(C) Itinerant trade and Fixed-shop trade
(D) Departmental trade and Chain trade

Internal trade's own internal split is between selling in bulk to a business buyer and selling in small units to the final consumer.

Check each option against whether it names a split within internal trade specifically, not a split of external trade or of retailer types.

Internal trade is divided into two stages based on the scale of the transaction and who the buyer is: Wholesale Trade, where a middleman buys in bulk from producers and sells in smaller lots to retailers or institutional buyers, and Retail Trade, where the final seller sells in small units directly to the individual consumer.

Option-by-option analysis:

• (A) Incorrect — export and import trade are sub-types of External, not Internal, Trade.
• (B) Correct — this is exactly the two-stage split of internal trade.
• (C) Incorrect — itinerant and fixed-shop are types WITHIN retail trade, not the split of internal trade as a whole.
• (D) Incorrect — departmental and chain stores are both types of large-scale retailer, a category within retail trade, not the internal-trade split itself.
