Right answer is (c) Creep Test

Explanation: Creep Test is used to measure tensile strength of plastics. In this the specimen is subjected to a static load. The results are noted accordingly for long term behavior of plastics. Blocking is the ability of two films to be in such a contact, so as to eliminate any air present in between the layers. WVTR and OTR are Water Vapour and Oxygen Transmission Rates.
