A beam of length L and flexural rigidity EI is simply supported at the ends and carries a concentrated load W at the middle of the span. Another beam of identical length L and flexural rigidity EI is fixed horizontally at both ends and carries an identical concentrated load W at the mid-span. The ratio of central deflection of the first beam to that of the second beam is
(a) 1 (b) 2 (c) 0.25 (d) 4
