It can also be as they had mentioned the specific material that is wood from which the table is made of and not of some other material like glass, plastic,etc.Likely,it should be specified the material of the shirt that is cotton.
But cotton os a type of cloth
Yes, answer is cloth. because as they are not talking about which type of wood is table made of. then as such shirt is made up of cloth. not of cooton. as described earlier
Its about the raw materials used...the way wood is the raw material for table similarly cotton is also the raw material for shirt
