The atom is considered to be more electronegative, when it has the tendency to get a slight negative i. e., delta negative charge on it, and the other atom gets a delta positive charge.

In the periodic table,

As we go left to right in the periodic table, the electronegativity increases,

and

As we go top to bottom, the electronegativity decreases.

Hence, from the option given in the question,

a. C--H, the electronegativity of both the atom is almost the same, but looking at the treads of the periodic table, Carbon is more electronegative than hydrogen.

b. C--N, the electronegativity of both the atom is almost the same, but looking at the treads of the periodic table, nitrogen is more electronegative than Carbon.

c. C--S, the electronegativity of both the atom is almost the same, but looking at the treads of the periodic table, sulfur is more electronegative than Carbon.

d. C--O, the electronegativity of both the atom is almost the same, but looking at the treads of the periodic table, oxygen is more electronegative than Carbon.
