Which of these is a geometric isomer of the above compound?

If you're talking about this geometric isomer (first image), then your answer will be the second image. This is answer letter C.

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
