Read the given paragraph and select the option that correctly fills the blanks in it. The female silk (i) lays egg which hatches into a tiny caterpillar. It feeds on (ii) and grows. When it is ready to enter the next stage in its life cycle, it first weaves a net to hold itself by secreting a proteinaceous fibre which (iii) on exposure to air. This is the silk fibre. The silkworm covers itself completely with this fibre to form a (iv) . At this stage, the larva is called a (v).
