Answer :The correct answer for (C₄H₁₀ )₃ N is C) TERTIARY AMINE .
The substitution level of nitrogen in amine or in simple words , description of carbon atoms attached to a given nitrogen in any amine is of 4 types :
1 ) Primary amine :
When the given nitrogen is attached to only one carbon then substitution level is known as PRIMARY amine.
Example : CH₃NH₂ : The nitrogen is attached to only one carbon (CH₃) . Hence it is primary amine
2) Secondary amine :
When the given nitrogen is attached to two carbons .
Example : (CH₃)₂NH : The nitrogen is attached to two carbon ( CH₃)₂ , hence it is secondary amine .
3) Tertiary amine :
When the given nitrogen is attached to three carbon atom .
Example : (CH₃)₃NH : The nitrogen is attached to 3 carbons atoms (CH₃)₃ . Hence it is a tertiary amine
4) Quaternary amine : when the nitrogen attached to 4 carbon atoms and amine posses a positive charge on it , its is known as quaternary amine .
Example : (CH₃)₄N⁺ : The nitrogen is attached to 4 carbons and nitrogen . hence it is quaternary amine .

The given compound is (C₄H₁₀ )₃ N has 3 groups of C₄H₁₀ attached to N , means 3 carbons attached to N , ( image attached ) . Hence it can be said that (C₄H₁₀ )₃ N is TERTIARY AMINE .
Hence correct option is C) Tertiary amine .
