a. lack a reproductive phase
b. contains hyphae
c. has spores contained in ascus
d. has spores contained in basidia
Answer is C. Truffles has spores contained in the ascus.
Explanation:
Fungi like yeasts, molds and mushrooms are eukaryotic organisms which acts as main decomposers in the environment. Black truffles are aromatic edible fungi which belong to the ascomycota phylum. They are expensive and normally seen in the southern Europe. The main feature of the ascomycota is the ascus, a sexual spore bearing cell containing spores called ascospores. Black truffles are round shaped with black-brown skin and has small pyramidal cusps. It contains tightly interwoven hyphae (long filament like structure) and numerous asci (spore bearing cells). Each ascus contains some spores called ascopores, which is specific to fungi classified as ascomycetes. Mushrooms belong to the basidiomycota phylum. They are also composed of hyphae and reproduce sexually via the formation of specialized cells called basidia which have spores called basidiospores.

Explanation:
1. The beam emitted travels along a straight path and it is divergent in nature. It has its radius increasing progressively as the distance away from the source of light increases.
2. It would be observed that the region where the bulb is positioned has denser light beam. This gets fainter towards the edges of the beam and away from the bulb.
