Explanation:

• Shadow puppets are flat figures. They are cut out of leather, which has been treated to make it translucent. Shadow puppets are pressed against the screen with a strong source of light behind it. The manipulation between the light and the screen make colourful shadows.
• Tholu Bommalata: Tholu Bommalata, Andhra Pradesh's shadow theatre has the richest and strongest tradition. The puppets are large in size and have jointed waist, shoulders, elbows and knees. They are coloured on both sides. Hence, these puppets throw coloured shadows on the screen. The music is dominantly influenced by the classical music of the region and the theme of the puppet plays are drawn from the Ramayana, Mahabharata and Puranas. Hence option b is the correct answer.
• Ravanachhaya: It is Orissa's popular shadow puppet form. The puppets are in one piece and have no joints. They are not coloured, hence throw opaque shadows on the screen. The manipulation requires great dexterity since there are no joints. The puppets are made of deerskin and are conceived in bold dramatic poses. Apart from human and animal characters, many props such as trees, mountains, chariots, etc. are also used. Although Ravanachhaya puppets are smaller in size-the largest not more than two feet have no jointed limbs, they create very sensitive and lyrical shadows.
• Togalu Gombayetta: The shadow theatre of Karnataka is known as Togalu Gombeyatta. These puppets are mostly small in size. The puppets, however, differ in size according to their social status, for instance, large size for kings and religious characters and smaller size for common people or servants.
• Yampuri: The traditional Rod puppet of Bihar is known as Yampuri. These puppets are made of wood. Unlike the traditional Rod puppets of West Bengal and Orissa, these puppets are in one piece and have no joints. As these puppets have no joints, the manipulation is different from other Rod puppets and requires greater dexterity.
