When we say that discovering theme is partly a subjective task, we are using which of the following meanings of subjective?

characteristic of or belonging to reality as perceived, rather than as independent of mind

being or relating to a grammatical subject

lacking in reality or substance

none of the above

characteristic of or belonging to reality as perceived, rather than as independent of mind

Explanation:

The theme is a fundamental element of a literary work. Although the author has certainly established a theme for his work, we can still say that discovering the theme is partly a subjective task, because the reader´s interpretation of the text might take him to unexpected conclusions and discover unforeseen ideas. The word "subjective" in this sentence refers to the way reality is perceived, how our interpretation of reality might differ from that of others. The word is not used in a derogatory way to mean something lacks substance, nor as related to a grammatical subject.
