The correct answer is - B) ATP and NADPH.
The products of the light reactions of the process of photosynthesis are the ATP and NADPH. The small amount of ATP produced in this process and the energy carrier NADHP are crucial for the functioning of the organisms that use the process of photosynthesis, and the reason for that is that these two are used by the organisms to create glucose, or rather sugars, in the process called the Calvin Cycle. The glucose is what these organisms use as their food, a food they they manage to make themselves, thus making them producers. If the light is missing, then the process of photosynthesis can not be performed because the formation of ATP's will be stopped, as well as the formation of NADHP, so the organisms will not be able to produce their own food.

Answer:
10 chromosomes/sister chromatids
Explanation:
Prophase is the first stage of cell division (mitosis). Prior to the cell entering the actual division stage, it undergoes a phase where it prepares its content and most importantly undergo the duplication of its genetic material (DNA). This DNA are found as chromosomes. It undergoes replication of its DNA in the S-phase of interphase stage.
Since Arabidopsis thaliana has 10 chromosomes, and each chromosome holds one DNA molecule, 10 molecules of DNA will be present in the mustard plant's genome. These 10 molecules of DNA will be replicated on another copy of chromosome which is identical to the template. This chromosomes are called SISTER chromatids i.e. replicated chromosome. Each sister chromatids are held together at the centromere and are considered one individual chromosome until they separate during anaphase stage.
Hence, at the Prophase stage, before separation, each sister chromatid (replicated chromosome) is considered as one chromosome. Thus, in the mustard plant with 10 chromosomes, it will possess 10 sister chromatids or chromosomes at the Prophase stage.
N.B: When sister chromatids separate during anaphase stage, they will be regarded as individual chromosomes.
The main function of the smooth ER is to make hormones and lipids.
