The simple answer would be to get the value of (using xsl:value-of)
the b element whose child c element is equal to 3:

  <xsl:value-of select="b[c = 3]" />

However, the b element holds mixed content. In a tree it would look
like (&#xA; indicates line breaks):

+- (element) b
   +- (text) 2&#xA;
   +- (element) c
   |  +- (text) 3
   +- (text) &#xA;
   +- (element) d
   |  +- (text) 4
   +- (text) &#xA;

So you want the normalized version of the (first) text node child of
the b element whose child c element is equal to 3:

  <xsl:value-of select="normalize-space(b[c = 3]/text())" />

You can drop the normalize-space() if you don't care about the line
break being output.
  
Cheers,
