  1. ᴘʜᴏᴛᴏsʏɴᴛʜᴇsɪs, ᴛʜᴇ ᴘʀᴏᴄᴇss ʙʏ ᴡʜɪᴄʜ ɢʀᴇᴇɴ ᴘʟᴀɴᴛs ᴀɴᴅ ᴄᴇʀᴛᴀɪɴ ᴏᴛʜᴇʀ ᴏʀɢᴀɴɪsᴍs ᴛʀᴀɴsғᴏʀᴍ ʟɪɢʜᴛ ᴇɴᴇʀɢʏ ɪɴᴛᴏ ᴄʜᴇᴍɪᴄᴀʟ ᴇɴᴇʀɢʏ. 

  2. Step-by-step explanation:

    Correct option is

    A

    ⊘ϵA

    B

    {⊘}ϵA

    D

    {7,⊘}⊂A

    a. ⊘ is present in A. So, ⊘∈A

    b. Another subset ⊘ is present in set A. So,⊘∈A

    c. 1 belongs to A, but not {1}. Hence {1} is not the subset of A

    d. 7 and ⊘ are present in A. ∴{7,⊘}⊂A
