An infinite number of identical capacitors each of capacitance \[1\mu F\] are connected as in adjoining figure. Then the equivalent capacitance between \[A\] and \[B\] is [EAMCET 1990]

• A.                    \[1\mu F\]
• B.                    \[2\mu F\]
• C.                    \[\frac{1}{2}\mu F\]
• D.                    \[\infty \]
