an object found in china is made of rock and metal and is estimated to be 4.5 billion years old. it is irregular in shape and contains many large gem - like crystals. these crystals are primarily composed of the mineral olivine. on earth, this mineral is mostly found in rocks from the mantle layer below the crust.
which image shows the object described above?
image 1: fukang, a meteorite
image 2: 67p/churyumov - gerasimenko, a comet
image 3: titania, a moon

Explanation:

The object is a meteorite (landed on Earth's surface), made of rock/metal, 4.5 billion years old, irregular, with olivine crystals. The first image (Fukang, a meteorite) matches: it's a meteorite (landed), has a rocky/metallic, irregular appearance with crystalline structures (olivine - related). The comet is in space, the moon is a celestial body, not a landed object with those mineral characteristics.

The image of "Fukang, a meteorite" (the top - left image)
