Boric acid is polymeric due to
(a) its acidic nature , (b) the presence of hydrogen bonds
(c ) its monobasic nature ,(d) its geomtry

Explanation

To determine why boric acid (H3BO3) is polymeric, let's analyze the options provided in the question step by step.

### Step 1: Understand the structure of boric acid
Boric acid (H3BO3) consists of boron (B), oxygen (O), and hydrogen (H) atoms. The boron atom is central and is bonded to three hydroxyl groups (-OH).

### Step 2: Analyze the options
1. **(a) Its acidic nature**: While boric acid is a weak acid, its acidic nature does not directly contribute to its polymeric structure.
2. **(b) The presence of hydrogen bonds**: Hydrogen bonding occurs between the hydroxyl groups of different boric acid molecules, leading to the formation of a network or polymeric structure.
