Step 1: Recall the relevant legislative amendment.
The Union Cabinet approved an increase in the sanctioned strength of Supreme Court judges by amending the Supreme Court (Number of Judges) Act.
Step 2: Identify the specific numbers approved.
The Cabinet approved increasing the judge count by 4, raising the total from the then-existing 33 to 37 judges (this figure includes the Chief Justice of India). The increase was intended to address the pendency of cases.
Step 3: Match with options.
Option (2) correctly states the increase was by 4 judges, from 33 to 37. All other options cite incorrect figures.
\[ \boxed{\text{by 4 from the present 33 to 37}} \]
