Study the following information to answer the questions given below: A company wants to hire young professionals where students of any graduate stream can participate in the drive. But company put some eligibility criteria. There are two rounds, round one consist of aptitude test and 2nd round is personal interview. 1) Student having no backlogs is eligible to participate in the drive. 2) Student must have at least 68 percentages in 10th and 12th. 3) Student having greater than 85 percentages in graduation without any backlogs are eligible for direct interview round. If the 1st or 2nd criteria not fulfilled then, 1) If a candidate has a work experience of 1 year in any field he is eligible to appear in aptitude round. But if the candidate has not clear his backlogs he is not eligible to participate in the drive. Amit a commerce student has a score of 69 percentages in 10th and 12th. He is currently working in an IT company for 15 months. In graduation he scored only 65 percentages and also clears his backlogs.

Consider the following statements for ductile fracture: 1. The material undergoes substantial plastic deformation with high energy absorption before fracture. 2. Presence of cracks on the surface of material initiates this type of failure. 3. Fracture occurs due to necking. Which of the above statements is/are correct? 
According to the fracture theory of the material, the critical value of the crack extension force, which makes the crack propagate to the fracture is called the fracture toughness of the material.
