Correct Answer: very intimate terms

Solution : The correct choice will be the first option.

The idiom hand in glove means to be in a very close or friendly association or partnership with someone. It suggests a relationship where individuals work closely together, cooperate seamlessly or share a strong connection.

For example, if two colleagues are said to be hand in glove, it implies that they work closely together, coordinating their efforts seamlessly.

Therefore, the answer will be very intimate terms.
