I cannot find the propositions, so I just define what an alpha particle is:
Alpha particles (or alpha rays) are a form of radiation emitted by unstable nuclei of great atomic mass (alpha decay). They consist of two protons and two neutrons combined into a particle identical to the helium nucleus, so they can be written 4He2+ (or 4α2+). (the nuclei will lose 2 positive charges and 4 atomic masses)
Unlike other particles, a Beta particle is the emission of an electron (or a position), and gamma rays (not a particle) is the emission of a ray photon very high energy light.
I hope this could help you with you answering the question.

<em>Growth factors of bacteria are compounds that are important for the growth of bacteria but which cannot be synthesized by the bacteria themselves. Without these compounds, the growth of bacteria would be limited or they will not even grow at all.</em>
These compounds which are usually organic in nature include purine and pyrimidine nucleotides, vitamins, amino acids, and hormone-like peptides.
From the options, only option d does not fall among the growth factors required by bacteria.
Hence, the correct option is d.
