          Answer & Explanation
         Answer: A) 1, 5 – hexadiene         
         
Explanation: 3 – Hexanol:

There is no alcohol stretch present in the spectrum. Therefore, the above structure is not suitable for the given spectrum.
 
Trans – 4 – octene:

There is no vinyl bending present in the spectrum. Therefore, the above structure is not suitable for the given spectrum.
1, 5 – hexadiene:

The vinyl bending and other stretches were matched with the above structure.
 
 
Hence, the c = c stretch, vinyl bending and  stretch were matched with the above structure.
 stretch were matched with the above structure.
Therefore, the given spectrum belongs to 1, 5 – hexadiene.
