1) Possible, Tensile strength increases with molecular weight. Therefore, linear and isotactic polymer will have the higher tensile strength.
2) Not possible both polymer exhibit same degree of increased tensile strength, however we do not have enough information to quantify exactly how much in order to distinguish which has higher value.
3) Possible in general network polymers have greater tensile strength as compared to branch structure due to increase number of covalent bond.
