To interpret inequalities like these, split the inequality into two parts.
For example, take choice (A).
A. 190< x <= 240
first read 190<x that means x is greater than 190 (but cannot be equal to).
Notice that x is on the "wider" side of the sign.
Then read x<=240, this means that x is less than, or equal to 240, since x is on the small part of the inequality sign, and the extra line makes the equality.
So, together, choice A is interpreted as
x can take values from 190 to 240, excluding 190, but including 240.
Based on this, you can attempt to find the correct choice.
