ya so in these type of cases try to give the answer which are definite like 100% true types.

For eg herex is in [2,4]

so A is true

option B is not definatly true as x may be in [3,4] or may be outside this . (What if x is 2 ?)

Option C is correct as all numbers between 2 and 4 will also be between 1 and 4 also

Thanks
