From the given options, select the OPPOSITE in meaning to the given word:

"Conscientious"

Irresponsible

The opposite of "Conscientious" is Option 3: Irresponsible.

Explanation:

Conscientious refers to being careful, diligent, and responsible in one's work or duties. Irresponsible is the opposite, indicating a lack of responsibility or care.

The other options do not convey the opposite meaning of "Conscientious":

Option 1: Mutual refers to something that is shared or common between two or more parties, but it does not represent the opposite of being conscientious.

Option 2: Scrupulous means being very thorough and attentive to details, similar to conscientiousness, so it is not the opposite.

Option 4: Meticulous also means showing great attention to detail, which aligns with conscientiousness rather than being its opposite.
