Answer 1

I hope the below method will solve your problem.
You dont need to edit the owl carousel js. The same method can be applied to Bx Slider also.

$('.owl-demo').owlCarousel({
    margin: 0,
    responsiveClass: true,
    smartSpeed: 500,
    dots: ($(".owl-carousel .item").length > 1) ? true: false,
    loop:($(".owl-carousel .item").length > 1) ? true: false,
    responsive: {
        0: {
            items: 1,
        },
        500: {
            items: 1,
        },
        768: {
            items: 1,
        }
    } 
})
