[A] 1 only

[B] 2 only

[C] Both 1 and 2

Answer: C
Notes:

A composite material is a combination of two materials with different physical and chemical properties.  

  • When they are combined, they create a material which is specialized to do a certain job, for instance to become stronger, lighter or resistant to electricity.  
  • They can also improve strength and stiffness.  
  • The reason for their use over traditional materials is because they improve the properties of their base materials and are applicable in many situations. 
  • Use of composite materials in indigenously developed aircraft (Tejas), missiles (Agni) and in defense and civilian sectors is poised for big growth, where Indian companies are set to get into manufacturing mode.
