Why is calling slave trade only a sea journey a historically weak answer?

Because it included a whole system of profit forced labour and inhuman sale

The governing concept is that the slave trade was a broad system of exploitation, not merely a voyage across the Atlantic. It involved capture or forced removal, sale and purchase, confinement and transport, plantation labour, colonial production, insurance, credit and commercial profit. The sea journey was only one stage within this larger network, and describing it alone hides the violence and economic relationships that sustained slavery. Option A is correct because it includes forced labour, profit and the inhuman treatment of people as commodities. Option B is false because ships were central to Atlantic transport. Option C wrongly gives the trade a religious purpose, while option D confuses it with taxation. A complete historical answer must explain the whole system.
