Answer:
Claudius concludes that Hamlet is not sick because of love but rather that he is planning something else. He thinks that love-sickness is not the cause of Hamlet's behavior.
Explanation:
In Act III scene i of the play "Hamlet" by William Shakespeare, Claudius, Ophelia and Polonius had met to spy on Hamlet and to see his behavior. Ophelia acting as the bait, she conversed with Hamlet and the after sometime, he left. The whole encounter was seen by Claudius and Polonius, Ophelia's father.
After Hamlet left, and they all have seen how he had behaved and talked, Claudius claims that love sickness is not the cause of Hamlet's strange behavior. Rather he thinks that "There’s something in his soul / O'er which his melancholy sits on brood, / And I do doubt the hatch and the disclose/ Will be some danger". He suspects him to be hatching some evil plan which also scares him, thus making him send Hamlet to England.
