    ...The added genes confer traits raning from longer shelf___(1)___ to pest resistance. The plants seem safe, but the environmental watchdog groups fear that the spliced genes might spread into the crops' wild relatives. In such hosts, the genes might be less benign- and harder to control
    1)
    a) length
    b) life
    c) duration

    "shelf life" is a common term used to describe how long something can stay fresh.

    The "host" here refers back to the crop's wild relatives.

    in this text shelf life denotes the length of time that these plants can be kept before they become useless
    2) what does host mean here?
    Here it means a plant that another plant lives on as a parasite
