The correct option is D His wife was already sufficiently supplied with the articles in question
The most common example of an 'implied agency' between husband and wife may be seen where the wife purchases household necessaries on credit. A wife who lives with her husband is supposed to have an implied authority of her husband to purchase goods of domestic necessity on credit. The husband is bound to pay the price of goods. But if the husband already sufficiently supplied his wife with necessaries, he would not be liable as an agent.
