Given below are two statements : one is labeled as Assertion A and the other is labelled as Reason R :

Assertion A : The H$$-$$O$$-$$H bond angle in water molecule is 104.5$$^\circ$$.

Reason R : The lone pair - lone pair repulsion of electrons is higher than the bond pair - bond pair repulsion.

In the light of the above statements, choose the correct answer from the options given below :

Match List - I with List - II.

	List - I (Molecule)		List - II (Bond order)
(a)	$$N{e_2}$$	(i)	1
(b)	$${N_2}$$	(ii)	2
(c)	$${F_2}$$	(iii)	0
(d)	$${O_2}$$	(iv)	3

Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R.

Assertion A : Dipole-dipole interactions are the only non-covalent interactions, resulting in hydrogen bond formation.

Reason R : Fluorine is the most electronegative element and hydrogen bonds in HF are symmetrical.

In the light of the above statements, choose the most appropriate answer from the options given below :
