Answer:
The correct option is (B) Cleistothecium.
Explanation:
- Ascocarp, also known as ascoma and ascomata, is the fruiting body of the phylum Ascomycota of fungi (kingdom Fungi).
- It develops from vegetative filaments (hyphae) following the start of sexual reproduction.
- Asci, which are sac-like structures found in the ascocarp and have the names apothecium, cleistothecium [cleistocarp], and perithecium, typically contain four to eight ascospores each.
- Apothecia are stalked and have an exposed asci and can be disk-, saucer-, or cup-shaped.
- The biggest apothecium in existence, produced by Geopyxis cacabus, has a cup that is 50 centimeters (20 inches) in diameter and a stalk that is 1 meter (40 inches) high.
- Because they are spherical, cleistothecia must break apart or rupture in order to release their ascospores. With an apical aperture for ascospore release, perithecia are globular or flask-shaped.
Hence, option (B) is correct.
