B - Boron
C - Carbon
P - Phosphorus

Carbon is the element that if combined with iodine, will have the greatest attraction for the iodine electrons.

In Carbon-iodine bond the  electron pair is pulled closer to the carbon than the halogen atom. Both element have the same electronegativity values, 2.5

Answer:

carbon, C

Explanation:

In order to attract electrons, the atom that combines with iodine should have a high electron affinity. Within the periodic table, electron affinity increases across a period and decreases down a group. Therefore, among B, C and P; Boron (B) is expected to have the least electron affinity, followed by phosphorus (P) and finally carbon (C).

Order of electron affinity:

C > P > B

Therefore, if combined with iodine, carbon will have the greatest attraction for the iodine electrons.
