• Sexual reproduction is a mode of reproduction where new organisms are produced by the exchange of genetic material during fertilization. 
• Vegetative propagation and budding are forms of asexual reproduction and there is no exchange of genetic material in asexual reproduction.

In asexual reproduction, a single parent is involved to produce offsprings by fission, budding, or regeneration. While in sexual reproduction, gametes are produced by both the parents which fuses to form a zygote.
Thus, the correct answer is option D.

When the tip of the seedlings was covered with agar gel and is placed on seedling, The hormones which were later found to be auxins move from base to the apex. Thus the growth of the seedling was in the direction of more concentration of agar. As they were kept in dark, there was no light for growth so the seedlings have taken agar gel as the source of growth. While in those seedlings whose tips were again placed back on seedling or drop of water was placed on top of each seedling, growth does not occur as there is no medium for growth.

• In sexual reproduction, two individuals are involved and there is the genetic exchange between the male and female. 
• As there is an exchange of genetic material, the offspring, won't have exactly the same material as either of his parents. 
• There will be a different genetic content of each offspring, every time. As a result, there is no genetic sameness instead, sexual reproduction leads to variation.

Asexual reproduction is a mode of reproduction in which single parent produces offspring and inherit their genes. Asexual reproduction never involves in ploidy or reduction. The offsprings will be an exact copy of their parent and their siblings as well.
Thus, the correct answer is the option C.

During gamete formation, there is meiosis in which mother cell divides into 4 cells having a half number of chromosomes. In fertilization, male and female gametes fuse to form a zygote having the same number of chromosomes as parents. Hence, the number of chromosomes remains constant.

In asexual reproduction, the only single parent is involved and progeny develops directly from its parent by cell division, fragmentation, budding, etc. passing the same genes from generation to generations. Thus offspring formed by asexual reproduction have similarities among themselves.
