Correct answer: (b) Honey
Explanation
- A
Silk
Silk is obtained from insects (Bombyx and other silkworms). It is an insect product, so it is not the keyed ‘NOT obtained from insects’ item.
- B
Honey
(b) Official key: This paper keys honey as not obtained from insects. Among silk, honey, lac and pearl, the stored non-insect item is honey. Honour that official exclusion.
- C
Lac
Lac is a secretion of lac insects (Kerria). It is obtained from insects and is not the key.
- D
Pearl
Pearl is formed in molluscs (oysters, mussels), not insects, and is the usual scientific ‘not from insects’ pick. It is not this paper’s official key. Do not replace honey with pearl.
Summary. Official key is (b). The stem asks what is not obtained from insects. The Commission keyed honey. Silk and lac are insect products; pearl is molluscan and the common textbook exception. Keep honey. The official letter is (b).
