What is the correct phrase showing contrast regarding dislike for a host?

The phrase "In spite of" is the correct choice to indicate contrast regarding dislike for a host. This expression is used to show that something happens or is the case despite a particular factor. For instance, if someone dislikes a host but still attends a party, you could say, "In spite of my dislike for the host, I went to the party." This clearly conveys the contrast between the feelings of dislike and the action taken.

The other phrases do not fit as appropriately in this context. "Despite of" is not grammatically correct; the correct form is simply "despite." "Although" and "even though" are also options for introducing contrast, but these phrases typically set up clauses containing both the contrasting idea and the resulting action, rather than the prepositional phrase structure that "in spite of" uses. For example, you might say, "Although I dislike the host, I went to the party," which correctly introduces a dependent clause but differs from the structure sought after in the original question. Thus, "In spite of" stands out as the most suitable phrase to illustrate the contrast effectively.
